All you need to know is this:
Mitochondria is the powerhouse of the cell.
+SwiftEquation LOL
+Mystogan Edolas Lol.*
+SwiftEquation For biology grammar is irrelevant.
hahah
LOL
The next one posting "Mitochondria is the powerhouse of the cell" will experience the wrath of Khan Academy :)
Lol😂
the mitochondria is the powerhouse of the cell
yes
Obviously
No
**are
A mitochondrion _is_ a powerhouse.
Yes 😂
such an artist! you draw it so easily 🌚💔
90%: Mitochondria is the powerhouse of the cell.
I love your videos! I can memorize definitions, but watching your videos helps me to truly understand the functions and structures. Thank you! Please keep making them!
Same!!!
Who needs school when u have khan academy :)
Third world countries without internet access
Adnan Ahmad Scolershit (Scolership)
I'm from north korea and yes we have.
Ballistic missles.
Xander Zyle Bercasio how you can enter youtube if u are really from north korea?,
My school used his videos lol
I still remember the day when mitochondria was no longer just the powerhouse of the cell.
What a magnificent summary. Neat diagrams. Cryptic and enthusiastic. Good teacher
That made for a great refresher for my ageing brain. Thanks 👍
The Mitochondria is the powerhouse of the cell!
Neylena Yes it is
+Neylena don't believe her. she is trolling us
he you
he you
Oh cool, nice
+Darkk Mane Powerhouse indeed, Mitochondria, is.
+Darkk Mane didnt expect to see you here
eyyyyy
what's the plural for mitochondria
Nelum Lucere mitochondrion
Yayy, my favourite cell organelle!
I am amazed that a Japanese movie/video game/book called "Parasite Eve" made me interested in this subject.
I always find it fascinating when different forms of organisms work together... It gives me hope for us as humans.
one of them engulfed the other. the mitochondria sound kinda like slave workers subjugated by the cell
@@winniethepooh8766 Yeah, it took me a while to realize it's more akin to what people do with livestock... It's disturbing.
Can't have nice things now, can we?
Your videos are fantastic. So clearly explained and presented :)
Awesome vid, helped me with my biology homework for Uni.
Mitochondria is the powerhouse of the cell.
Love this video.....tells us so much more than our text books!
Thank you so much, this is a lovely way to learn and I can't belive the amount of information I didn't knew about mitochondria
:*
I like your video. You helped me before my biology to understand mitochondria. Thank you so much.
i love khan academy ever since they helped me understand application of nash equilibrium
96% of comments consist of "The Mitochondria is the powerhouse of the cell"
People trying to be funny
there is often severe muscle wasting in people with cancer.
one theory is called: Nuclear Meltdown, and it concerns mitochondria degradation.
Michael Wiggs and his crew made a mouse model with implanted cancer cells and monitored the health of the mouse and many indications for four weeks, which is when the mice would be euthanized so they didn't die from the cancer.
many of the indicators they monitored did NOT show a steady degradation, but instead would show minor degradation for the first three weeks, and then a LOT of degradation in the fourth week, and the mouse would be near death.
But, when they monitored mitochondrial function, they noticed it degraded in a stepping stone fashion.
this indicates that mitochondria show early changes we can investigate to see if we can intervene in the degradation process before severe muscle loss becomes deadly.
Khan academy is the best i swear

What he said about the spermatic mitochondria being dissolved by the egg... That's not what happens.
Actually during fertilization only the nucleus of the sperm passes the layers of the egg and enter it. The tail and rest of the part of the sperm gets dissolved in the uterus (or more precisely the ampullary-isthmic junction of the fallopian tube cuz fertilization takes place over here)
Amazing video! I now get the mitochondria and I get how we keep learning more each day- week -year! You have a gift of teaching- thank you!!
Anakin had the highest midichlorian count. Midichlorian are like mitochondria but more bad ass.
And also called as ATP factory of cell
I agree. My mind is boggled, I only recently found out mitochondria have different DNA than the cell nucleus. Somehow, this explains the origin of life. :)
tnx!! u r greate!! i am from Israel/ and i waching u!
I love the voices of these videos
I don't know how anyone with a clear and healthy mind can possibly believe that something as complex as life came up by accident.
I mean maybe there was an intelligent designer, but not the divine one that most people think about.
My poor brain cells have thought about that for dayyyyyyys on end!
i have a question. are all the videos in the playlist covering the whole sat biology subject test
you almost make this interesting :O
Love these videos...as a biological student
My imagination is not equipped to handle the “ evolution” of the mitochondria but the facts about it were great thanks!
Thank you! I was quite baffled with the textbook explanation of the mitochondrion
Thank u for helping me spiritually awaken
It WAS mind blowing,just like you said, THANK YOU, especially about the origin, being bacterial... Great explanation and presentation! Subscribing!
Great presentation!
I'll sum it up in a sentence: The Mitochondria is the powerhouse of the cell.
How did the cells work before mitochondria took residence?
Colin CK they consumed
The same way prokaryotic cells still do now.
Electron microscope mitochondria( shown in the video) is round because it is daughter mitochondria, where as mature mitochondria is elongated.
PLEASE DO A VIDEO ON PLASMOLOGY
such fine tuning and intricacy. to say it doesnt have a creator and that it came from chaos is just very illogical. it is indeed a sign we have a creator. us, the cells we are made of, the universe. Allah creates as He wills
Mitochondria is the house of the cell power
you guys save the world...
so,should we stick to the old model of the mitochondria or leave it and understand the new one?
U a the best
Let’s keep it family friendly
Great video . This stuff is extremely fascinating. Thanks
Thank you learnt a lot more than just from the text
You are Fabulous., the way to learn You are amazing.i fell so much pleasure to get more information From you. But i want further detailed study from science bcoz I love science a much. Any way thanks bro
Mitochondria is the power of the cells
if you poke a hole in the inner membrane of the mitochondria so that proton could move freely acoss it, what would happen to the proton distribution?
Someone needs to remix Sal saying "straddling the christy"
good job mate it may not from our ancestor originally, this mitochondria might just be eaten by mistake
Agree +1
How does the synthesized stuff go into the Mitochondria? Is there a membrane? If so, what's the process, involving hypo and hyper?
Dump the Darwinian fable. This is intelligent design!
Yay! ❤
Khan is on you tube!
i i i love ur fascinating explaination and diagrams 😊
Mitochondria is the location of oxidative phosphorylation.
Alright mr. Fancy pants no need for excessive jargon here
THE MITOCHONDRIA IS THE POWERHOUSE OF THE CELL
I understand thriving mitochondria have not been found outside a cell. I suspect that they have not been removed from a cell and have survived.
Anthony Lusich the mitochondria is like a piece of history, they are ancestors of current day bacteria that descended from mitochondria that thrived. You cannot remove mitochondria from a cell and expect it to live, they are dependent on the cell for glycolysis in order to produce the energy we harvest.
Is how are u explaining is different from explaining it as Histology?plz answer
I wanna join the wave: Mitochondria is the powerhouse of the cell
Mitrochondria,cell membrane,cytoplasm,chlorplast,chlorphll,cell wall,ATP,cell are my bffffff ckr 14 year
i have a question regarding the cell transportation.. am i just want to ask .."how mitochondria transport ATP to the carrier protein in order for the molecule get outside and inside of the cell membrane from low to high concentration??
This is a really great vid thank you 🤓
Amoeba Sisters is better in a more fun and entertaining manner.
But you do a very good job as well.
And just think, non-teleological flukes of nature designed and built cellular power plants. Praise Darwin. Blessed be his name.
Thanks so much!!! It's awesome!
Is mitochondrial DNA expressed to produce the proteins in the mitochondria or is it useless?
i think it produces its protein
Yes, mithocondrial DNA can produce proteins exclusivly for this organele
Your a good artist
I'm studying about the cell in gr8 but u talk about other things we didnt learn yet :/ gets me sometimes confused.
why is bleach studying????
Tirtle // LB Can't argue with that! Well ill just drink myself if u dont mind
I actually liked for the profile pic lllol
Geaat explaination but Google says"However, mitochondria cannot survive outside the cell."
Ok great I think I get it now but which organelle is the powerhouse of the cell?
is this the only guy who works at khan academy
Housecell of the power is mitochondria
thanks for the video!!
Sir oxysomes is also known as F1
please make one video about plastids in detail.
This guy is a legand
Would it be possible to modify the mitochondira to accept electrons from a metal wire instead of using NADH ? This way all cell could be powered without nutrients but with pure electricity. Is there any research on that ? :) Just curious.
What if .. solar systems are macro-cells? The larger u get, the more complicated, or, the more extreme it becomes
Why is mitochondria called autosymbiotic organelle???
Because it has dna that can regulate their own synthetic protein that ribosom do inside of it
Please make a video on Exosomes. Thanks
Thank you so much
Thank you!
Thanks alot♥️😍😊
The midichlorians are powerhouse of a Jedi
The power house is the cell of the mitochondria
Good stuff. Im a dissabled animator who has a whole gang of lowly paid animators...i know how much adsense pays...but i could perhaps start small....or just chop up animation modeling methods. Thanks for work.
D
Membrane bound cell organelles.
Such fascinating things being explained but this comment section is a disgrace. Hopeless
My exact thought.
@@karinafang6064 how is this hopeless? we know the most important thing... THE MITOCHONDRIA IS THE POWERHOUSE OF THE CELL.
@@skizze.. Knowing that one sentence does not mean you know anything about mitochondria. That's way to vague for such an amazing organelle.
Help me what's this program ?
Record and drawing like you ?
what is the difference between the cytosol and cytoplasm??
Wonderful😎
oh i know now Mitochondria is the powerhouse of the cell :)
Can anyone tell me do proton gradient h+ ions leaks from porins (the hole of outer membrane) if so then how will the gradient will develop
