I think the main reason why we concentrate more and in turn learn more with these tutorials is that obviously they're one on one ... no other students which introduce new questions ... no other distractions ... such as room lighting ... people moving in class and outside of class, but the main reason is due to us reading the teachers facial expressions ... reading facial expressions, I think, by personal experience, deviates our thinking a LOT.
I remember watching your videos in high school to pass my biology tests. Now I'm here, after graduating college and working in biotech, still learning. Thank you!
I have a test over this and the Calvin Cycle for my Bio class... When I left class I didn't understand either of them even the slightest bit. Now I do. You are very intelligent.
I'm studying for my exams and these videos are the most amazing thing to help me review without reading each and every single one of my notes, thank you!
Thank you sooooooo much 🙌🙌🙌 why would I waste an hour trying to understand a convoluted chapter when I could come here for you to concisely sum it up in 20 minutes. I CAN NOT STRESS ENOUGH HOW MUCH YOU SAVED MY BIO GRADE!!!
I love your videos because I'm a visual person. Thank you so much for taking the time to share your knowledge =) Amazing that your videos been up this long and has accumulated no dislikes =) Keep it up!
My first day of college chem 1 years ago, the professor detonated a 2 foot diameter balloon filled with hydrogen and oxygen gas at the front of the lecture hall. I swear I felt the walls shake when it exploded, and I'll never forget it. That's why I understand what you mean when you say it's hard to oxidize water, and it's pretty miraculous that a protein complex can do it with just an input of photons.
You are an awesome teacher Sal! I am sometimes impressed of how well you know each topic in each of your videos. Another thing that makes you a great teacher is that you always maintain the attention of the person watching the video, and that you know how to emphasize things that are important. Seriously, you are a person to admire, greetings from Guatemala!
You are the best!I just spent my whole day studying a book about photosynthesis and I finally understood the whole process watching your videos!!thanksss
immense wisdom incoming (im sorry khan academy if this sinks your youtube channel): THE MITOCHONDRIA IS THE POWERHOUSE OF THE CELL thankyou for your applause, its nothin really
I love this narration. As the video goes on, the gravity of the absolute marvel nature and our environment really is can be heard in his voice. No matter how many times i listen to this process, I cannot believe the wonder of our planet.
I think you're right with that, since choloroplast does essentially create sugar (via Photosynthesis) and mitochondria also makes energy too!! Mitochondria and energy is to do with Respiration though, but the plant has them both, but they're both different organelles which work on different processes!! Sorry if i made you more confused, but what you said does seem right :D
I would really like to thank you for creating this video. It has helped me tremendously in understanding the complexities of photosynthesis, and you make science exciting. I have a HUGE mid-term college biology exam on this very process, and I promise you that your video is going to impact my grade significantly. Thank you so much for your contribution to education! I will be sharing this video with my peers so they too can benefit. You have my gratitude.
he saved my life i actually thought that i cant learn this in my whole life and i was actually very upset that i will fail the exams but he made it soo clear in 20 minutes that i cant stop smiling em enjoying this thing now its soo cool
You are right, chloroplasts make glucose and mitochondria make energy, but in the process of photosynthesis, energy is also made (by the end of the elecron transport chain), then the next stage which is the calvin cycle, will be dealing with the production of the glucose... this video is focusing only on the first stage of photosynthesis :)
I think you've really set a precedent for teachers. They should be able to teach it in this way if they course touches on this. Other than that, I love you. hahaha.
photophosphorylation. Photo meaning light, and phospho meaning phosphate/"phosphorus". Basically, energy from a photon (light) is being used to add a phosphate to "something". That something, is adp. A~P~P (ADP) + P (Phosphate) + Energy (Photon) --> A~P~P~P (ATP)
HAHHA I love that bit about "well that makes you wonder what we might evolve into" when he is talking about the single celled organisms turning into multicellular
Hey Khan, thanks man. :) I started off creeping on your math video's, and am now discovering that you're good at, well, everything. This is an excellent supplement to my studies.
So I’m a middle schooler and I couldn’t study photosynthesis not because it’s complicated but I had questions and I felt the process was vague and I had multiple questions going on about it,I watched the photosynthesis series and I must say I understood and my confusion faded that might help too in upcoming years thank you khan!
Sal made a mistake early in the video when he said one stack of membrane bound sacs(thylakoids) are grana. MANY stacks of thylakoid are called grana. ONE stack, is only called a granum.
And my exam is just 5 hours away, including the time required to change into uniform, travel to school, and ofcourse- the boring school assembly before the exam! And yeah, I have to study whole photosynthesis!!!!
I really appreciate you taking the time to do these videos, they have really brought all the info. full circle for me and I feel like I have a good understanding of everything now!
I would kill if you could post the end picture (where you show everything we've drawn) as a pdf for studying afterwords. Thumbs up so he notices, please.
SO after learning Photosynthesis, and Cellular Respiration in one 50 minute lecture from my professor who loves to think she can simplify massive chapters into one lecture so we cover everything for the exam, I come to you to ACTUALLY learn and translate her jumbled confusing notes using the information I obtain from you. I wish you were my professor. You would probably challenge us but be fair enough to remove the stupid curve that only hurts people if everyone does too well . . .
omg i have found myself always watching your videos because you make it seem so easy and i actually understand it in so little time compared to in class lecture ahhh you're a lifee saver lol exam in a few hours thank youuuu !!!! :)
Remember the days when photosynthesis was just a long word for plants making food with sunlight?
I'm probably not the only one browsing comments while the video is playing... We should stay focused xD
LOL ah yes
Ya around the time we thought we thought we would become doctors when we grew up 😭
Good old times...
issues of reductionism
Goodness this guy knows everything doesn't he
he really does
That's for sure
I'm amazed of how much knowledge he has and how generous he is to share it with us. Bless him!
I think the main reason why we concentrate more and in turn learn more with these tutorials is that obviously they're one on one ... no other students which introduce new questions ... no other distractions ... such as room lighting ... people moving in class and outside of class, but the main reason is due to us reading the teachers facial expressions ... reading facial expressions, I think, by personal experience, deviates our thinking a LOT.

Oxidation Is Losing, Reduction Is Gaining. OIL RIG
LEO GER
LEO the lion says GER
I thought this was an awesome way to remember
Reduction is gaining an electron or gaining a minus. Since a minus is less, it is being reduced
I spent 3 days on photosynthesis in class, reading the textbook and having lectures, and finally this makes sense. Thanks so much!
Do you still remember it?
i really appreciate the precise language Khan uses elucidating complex subjects!
Yeah he elucidates well
I love your videos. You do not talk to fast, you repeat yourself, and you use different colors. It helps me sooooo much! Thank you
Gosh, I totally get it now! Mr. Khan, something about YOUR way of explaining as absolutely enthralling and mesmerizing. You are meant to be a teacher!
I have a test over this and the Calvin Cycle for my Bio class... When I left class I didn't understand either of them even the slightest bit. Now I do. You are very intelligent.
Feeling nostalgic listening to his voice
You are an absolute life saver. Whenever I get confused by the AP bio text book, I come to you. Thank you so much!!!
*pays 50k for an education worse than a youtube channel*
Miles Veney what topics does he teach that is degree level?
@@hazmo4423 this?
Abhi This isn’t undergrad-level, maybe highschool lvl at most
jojibot As an undergrade I can prove you wrong
@@jojibot9193 This topic is covered to the same extend in every intro to bio course (1st year)
my teachers now simplify everything and we dont have the time to go into detail and so i easily get confused. thanks khan.
The hypothesis is called the endosymbiont hypothesis if anyone wanted to look it up. It's super interesting.
+Ashrin Jan was looking for this thank you!
I'm studying for my exams and these videos are the most amazing thing to help me review without reading each and every single one of my notes, thank you!
How’d the exams go?
God bless this man. Sal has saved me in so many classes
this is the most helpful thing i have ever discovered in my entire life. can't tell you how much this made sense and helped me for my biology midterm.
Gosh i would love to be a teacher like him
A concept so tricky , made crystal clear in 20 mins. Perfect :)
So did you become a teacher?
Thank you sooooooo much 🙌🙌🙌 why would I waste an hour trying to understand a convoluted chapter when I could come here for you to concisely sum it up in 20 minutes. I CAN NOT STRESS ENOUGH HOW MUCH YOU SAVED MY BIO GRADE!!!
Seriously, your videos are amazing! They make everything so much clearer than a text book ever could. Please don't stop!
I have a test on this in an hour. I have learned more from this than I have studying for 9 hours last night
The world needs more teachers like you!
Someone get this man a Nobel's price or something
I love your videos because I'm a visual person. Thank you so much for taking the time to share your knowledge =) Amazing that your videos been up this long and has accumulated no dislikes =) Keep it up!
Thank you so much. I have a biology test today, so I kept watching your photosynthesis videos over and over.
My first day of college chem 1 years ago, the professor detonated a 2 foot diameter balloon filled with hydrogen and oxygen gas at the front of the lecture hall. I swear I felt the walls shake when it exploded, and I'll never forget it.

Holy crap you are like a bazillion times better than my teacher. My teacher just reads off a powerpoint. Thank you!
I love how this video has 0 dislikes. It's because it's flawless :3
SOMEBODY GIVE THIS MAN A MEDAL
I am able to workout and understand these concepts (by listening to them on my phone) all at the same time - thank you Khan
easily best bio teacher ive seen. even if i studied the material before watching, your vids really help me remember on exams
@khanacademy they really aren't kidding...
you're the only reason i've passed ( with mid 80s!) grade 11 and 12 university bio!
6:00 Sal almost got into some deep philosophical stuff here
We will involve into X-men, obviously.
what ,that is SO COMPLICATED , this man knows everything
you saved my life!! wish me luck on my aerobic respiration, anaerobic respiration, and photosynthesis test :)
Woah. that, is deep!! I Wonder how great are scientists.
And a 9th grader has to learn all this!😳
THANKS GOD THAT KHAN ACADEMY EXISTS !!!!!!!
I've been using your channel for A's since 2nd grade, keep up the good work, you're a life saver
You are the best!I just spent my whole day studying a book about photosynthesis and I finally understood the whole process watching your videos!!thanksss
This is the coolest science I've ever studied, it's really like an engine. Makes me think of some Victorian industrial engine.
these videos are really helpful I mean I can understand everything without reading some boring textbooks thank you soooo much
immense wisdom incoming (im sorry khan academy if this sinks your youtube channel):
THE MITOCHONDRIA IS THE POWERHOUSE OF THE CELL
thankyou for your applause, its nothin really
wow, if you like made videos for every subject i think i could quit school and return during my examinations. in short, YOURE AMAZING! GENIUS
I love this narration. As the video goes on, the gravity of the absolute marvel nature and our environment really is can be heard in his voice. No matter how many times i listen to this process, I cannot believe the wonder of our planet.
Seriously, thank you. You made it seem a lot easier.
You dont know how much you helped me for my finals tomorrow with this video!
Im totally recommending you to my teacher :)
I think you're right with that, since choloroplast does essentially create sugar (via Photosynthesis) and mitochondria also makes energy too!! Mitochondria and energy is to do with Respiration though, but the plant has them both, but they're both different organelles which work on different processes!!

Mr. Khan deserves Nobel Prize 💝💝💝💝💝
it took my teacher 2 weeks to teach what this guy taught in 20 mins...
actually 20 mins and 15 seconds
FadilNjr actually 20 minutes and 16 seconds
John Nelson the weirdest thing is that no one asked
he saved my life i actually thought that i cant learn this in my whole life and i was actually very upset that i will fail the exams but he made it soo clear in 20 minutes that i cant stop smiling em enjoying this thing now its soo cool
The best quality!!! Even I haven't learned anything about photosynthesis I still understand this. Thanks Mr Khan
This is a very helpful video! I'd recommend the 1.25X speed if you're short on time.
+Baula Morcos I watch these on 2x speed with subtitles. Talk about efficiency.
cuz OBVIOUSLY the best time to actually study and catch up on this material is right before an exam or a homework is due :P
jesus christ its jason bourne
2X baby
You saved my life for International Baccalaureate Biology Examination. Thankyou.
You are right, chloroplasts make glucose and mitochondria make energy, but in the process of photosynthesis, energy is also made (by the end of the elecron transport chain), then the next stage which is the calvin cycle, will be dealing with the production of the glucose... this video is focusing only on the first stage of photosynthesis :)
THANK YOUU!!
I really undestrood you better than the biology classes of 1 semester!!
I think you've really set a precedent for teachers. They should be able to teach it in this way if they course touches on this.
Other than that, I love you. hahaha.
I hope that one day, all teachers become at least as half as good as you Mr. Khan.
i learned more than i have the whole year with this video! thank you so much! defiantly worth watching!
you saved my life. wish me luck on my atp/photosynthesis test :)
this guy iz just great
he has transformed the lives of so many peopl
photophosphorylation. Photo meaning light, and phospho meaning phosphate/"phosphorus". Basically, energy from a photon (light) is being used to add a phosphate to "something". That something, is adp.
A~P~P (ADP) + P (Phosphate) + Energy (Photon) --> A~P~P~P (ATP)
This guy is amazing, so knowledgable and easy to follow! Thimbs up all the way!
Sir, consider yourself a life and grade-saver.
Thanks so much for explaining all the chemistry behind what goes on!!!!!!! So much more detailed than my biology book!
HAHHA I love that bit about "well that makes you wonder what we might evolve into" when he is talking about the single celled organisms turning into multicellular
im literally thankful for this guy...like..icould hug him!
Hey Khan, thanks man. :) I started off creeping on your math video's, and am now discovering that you're good at, well, everything. This is an excellent supplement to my studies.
You sir, just saved my biology final. Also, your enthousiasm is incredible!
2 ppl are jealous of how well and clearly khan explains this
So I’m a middle schooler and I couldn’t study photosynthesis not because it’s complicated but I had questions and I felt the process was vague and I had multiple questions going on about it,I watched the photosynthesis series and I must say I understood and my confusion faded that might help too in upcoming years thank you khan!
Man! You make a heck of a teacher!!
covered every concept in my slides in half the time and it was interesting...Bravo
Sal made a mistake early in the video when he said one stack of membrane bound sacs(thylakoids) are grana. MANY stacks of thylakoid are called grana. ONE stack, is only called a granum.

I really appreciate you taking the time to do these videos, they have really brought all the info. full circle for me and I feel like I have a good understanding of everything now!
i know you get this alot...but you saved my life, sir.
you're the coolest person on the internet thank you
you, sir, explain everything better than all my university teachers put together! thank you :')
I'm sad that I descovered this a month before my university entrance exam, the way you teach is amazing that I would've given you my School fee🙏🙏🙏
I would kill if you could post the end picture (where you show everything we've drawn) as a pdf for studying afterwords. Thumbs up so he notices, please.
hey dude why do you know almost of everything
+adriann caballes Sal has degrees from MIT and Harvard. He's just that smart.
Only one word for you sir...
Thank you very much 🙏🙏
God bless you 🙏🙏
SO after learning Photosynthesis, and Cellular Respiration in one 50 minute lecture from my professor who loves to think she can simplify massive chapters into one lecture so we cover everything for the exam, I come to you to ACTUALLY learn and translate her jumbled confusing notes using the information I obtain from you. I wish you were my professor. You would probably challenge us but be fair enough to remove the stupid curve that only hurts people if everyone does too well . . .
Man you were so happy about this being the only natural process where even water can get oxidized.
Thank you so much for these. You are helping me pass my BIO 1510. It's pretty cool you sound like Dustin Hoffman.
got my graduation test in biology tomorrow - thanks a lot
suuuuuuuuuuuuuuuuuch good videos. you are the reason i'm passing grade 12 advanced bio!
That's why khan academy is the best wuhoooo. Awesome
This guy has taught me more than my Bio teacher has...
i can listen to this man all day. :)
You saved my grade. Really, thank you SO much.
No words BRILLIANT........❤
I Love Ur Videos.
Mann I wish u were my teacher.. Although I don't think I was supposed to go that in depth thanks!!!!
omg i have found myself always watching your videos because you make it seem so easy and i actually understand it in so little time compared to in class lecture ahhh you're a lifee saver lol exam in a few hours thank youuuu !!!! :)
I wish u were my teacher....i alws found dis thng so hard
THNX
You teach better than my sch teacher.
