Has any one told Khan he has a good voice for this stuff. Thanks for the vid.
Better call him Mr.khan
endoplasmic reticulum sounds more like a harry potter spell than anything
Soooooooooo true !?!
😂😂😂
Yeah it sounds like Expecto Patronym..^_^
That’s probably because it’s partly Latin
Almost all the spells are just words in Latin
Stop being unoriginal and annoying
LMAO
Laughed with that thing you said about the endoplasmic reticulum sounding good as a band name! Haha your videos are the best. in time for my exam in a few days, thank you so much!
The thing I like about Sal is his thoroughness. He really truly explains everything and that is why his videos are great.
Absolutely! What a blessing.
Are you intentionally making these videos right in time for my exam next week? Gotta love what you do!
Its been 6 yrs yo did u pass?
@@mayasmansur9390 😂😂
did you pass bro?
did you?
9 yrs jesus u feel like I'm a time traveller anyways did you pass ?
'perhaps an even better name for a band' haha cutest thing I've ever heard ;)
4 minutes and 30 seconds into the video:
''This is what we are going to focus on in this video"
Thanks for the heads up
The beauty of these videos is the background introduction. One need to learn that for better presentation.
I personally feel like the introduction is really important because it's a review of the topics already learned that lead up to this concept. It shows how they all fit together in a sequence :)
I will name my next dog Endoplasmic Reticulum just because it sounds cool.
😂 😂 😂
@cardogkitchen lol
😂
name one golgi too
@@extremelyhappysimmer golgi sounds a nice name tho
These videos you upload veritably help to understand the bigger picture of a certain event in a cell. Making it possible to dig deeper into transporters etc. in med school. Thanks!
wow I never knew that cytoplasm is everything in the cell ;___;
Me too
Except the nucleus
Thank you! I understand you much better than my books that are in my native language.
I agree
omg same here i can't even >>:'v
same broo
You are just the best. Your voice is strong, you explain everything so plausible ( and english is not my first language ) and I love!!! how you repeat things while you write them out. This way I don't even have time to get
distracted. Its such a great way of teaching. Thank you so much!
Mr. Khan., thanks for yet another great illustrative video.
This was so clear, before I watched this I was so confused what a Lumen was, and the internet did NOT help. THANK YOU!
I'm happy that he clearly explained the fact that the nuclear envelope consists of two separate membranes (for a total of four leaflets). Great job!
Was hoping for something a little more complicated Didn't add anything to my knowledge. Need more detail i.e COPI and II vesicles and vesicular tubular clusters or more about the Golgi-E.R retrieval pathway were soluble proteins require a receptor for their 4-amino acid recognition sequence (KDEL).
This is more of an high school video, and it is in the SAT Bio Test playlist like you see, so I don't think it should be that advanced to get into such details.
شكرا جزيلا
Thank you so much! Always informative and accurate!
4:14 The relevant part in accordance to the title.
khan this video is awesome keep it up but i just have a little note which is when you drew the ribosome you drew a circle but you didnot clarify that ribosomes donot have any membrane so people would misunderstand thank you for your work!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I love how you explain this lesson. This helped me understand the process😄
Really kind description about Golgi apparatus. Thank you for this video.
thanks so much! Watched it 2 times, I understand it now.
Keep doing what you're doing, really helpful. I have a confusing teacher.
Does anyone know if I’m just starting on these cellular things which khan academy vid shd i start from to get the fundamental idea
really useful for my studies. Thank you !
Man i could swallow all the lectures given by him ! Now i love Biology !
after watching this video twice, i now possess great intellectual capacities. i can cause natural disasters by sneezing.
Very hood video, thank you! Finally I understood how ER work, and why.
Thank you! This video really helped.
thank you very much.
is there any benefit from connection between perinuclear space and lumen of endoplasmic reticulum?
Extremely clear and concise thank you!!!!!!
You're such a bless to humanity !
THIS IS GREAT!
Ur lecture make this topic so easy
east and west khan academy is the best
The mRNA does not find a ribosome associated with the endoplasmic reticulum. Translation always begins in the cytosol, then when the ribosome gets to the signal sequence of the mRNA, then the ribosome and mRNA attach to the endoplasmic reticulum and translation proceeds there.
These vids are great!
very good for me! tks u so much
Thank you, so helpful
The best you are, Khan academy.
Why are you not teaching my class!!! This makes so much more sense then how my professor explained it... Thanks you!!!!!
thank you brother that was useful
Thank you so much.
better than my lecturer :) thanks for the video. (y)
so it's effectively a quadruple lipid layer?
You are a grade-saver, sir
thank you
What happens to the protein inside of the ER? Does it just get wrapped up and sends it to places? And where else does he proteins move inside the cell? (Besides the golgi body)
THANK YOU & PEACE
finally understood why some proteins are translated in cytoplasm and some in ER! :D
Thank You
nice veido, and detialed explanation. But dont be nervous, you can do better!
thank you!!!
Thank you !😍
You are doing a great job. Please take the following as a very minor suggestion: I, for one, would appreciate les re-iteration in the dialog. This may only be me, so please take with a grain of salt.
wowsers this is awesome
Thanks a ton
So simple yet so complicated
Yes! Yes! Yes!
Great sir thanks
idk why but i haven't been getting sound on khan academy videos inside the site and here on youtube, is it a privacy thing?
Sal...you Rock 🔥🔥🔥🔥🔥
so is the cytosol the same as the cytoplasm, its just cytosol is more specific meaning out the substance between the organelles, or do you know have to know them both? and would you be penalised if you didnt?
Lol cytosol is everything that surrounds the organelles of the cell meaning without the Endoplasmic reticulum, nucleus... While cytoplasm is everything in the cell as a whole
Wow.....I used to think cytosol and cytoplasm are the same thing.
Actually..i have a confusion ..golgi is also formed from the budding of SER and also modify the proteins coming from ER..?
7:01 in this time ur laughing 🤣
Now that I think of it ENDOPLASMIC RETICULUM is actually a really good name for a Band😂😂👍👍
Nisa_Tandon Bands a-make him dance..
students can understand 100 percent concept, by watching your video
thanhx sir☺☺
Sir khAn your voice is awesome👌👌👌👌👌
you sound like Kronk from Emperor's New Groove and it helped me get this so thanks lol
Understood everything
Omg golgi hma matag very nice explanation
When you put it on x2 it sounds like he repeats the phrase 10 times. Or x0.25.
Domo Arigatogozaimashita Sal Khan! Watashi wa anata ga shite iru koto ni totemo kansha shite imasu! Watashi wa anata no oshie no naka kara nihongo o manabimashita!

Do the Rough E.R. and the smooth E.R. look different from each other?
Yes Smooth has no Ribosomes while rough do have them(like circular dots on them).
Is cell membrane only enlarged by extrusion?
i can't believe i found the videos my high school teacher showed us. He wouldn't even teach, just show this freaking videos
The sir like a week and like after disease 😒😑 but enthusiastic
thanks :)
When I read in class 5 to 10 .I have to read to provide money but now I am 11 and I learn many things without money
Thank you so much this helped so much
The dutch subtitles were even more helpful XD
good
Correct me if I am wrong, but I think that PROTOplasm is everything inside the cell, which Sal confuses here for CYTOplasm, which is the gel like fluid around the organelles.
Cytoplasm= includes everything in the cell except the nucleus. Cytosol= soluble part of cytoplasm (gel-like fluid)
Is it a bilipid layer or lipid bilayer? If bilipid, what are the two lipids? "Bilipid layer" yields nothing in a search.
We've been told to give a presentation on this and I honestly don't know how I would go about presenting without knowing the stuff going on.
Tldr: Idk anything and I'd be in a pickle without Khan Academy 😂
Can i study from this to the emsat exam?
All on a sudden biology had become fearful and boringstuff for me.Thnx for making me enjoy it again.
Nice
so after the mRNA spits out the protein into the ribosome, it still goes out to the cytosol as drawn in the picture, but what happens to it?
My Kids can learn from you
This is beautiful. Thank you Khan!
The nucleus is surrounded by a double nuclear membrane and each membrane is a bilayer. Well is it the same as a phospholipid bilayer?
i think
+alrayyaniQtr Yes, it's a double layer of phospholipids
it's not the same
It has two double layers of phospholipids.
Hmm did u missed the point that the protein that join the golgi body carbohydrate is added to form glycoprotein ?
Hello sir may i save your vid
Insaene in the Memebraene!!
Thank Q....I find a name for my band............
I wish i would be compatible to your pronounciation
Why cell synthesise protein when we can have it by food?
Awesome:)
this is from khan academy , he explains very well
so... did you make a band named Endoplasmic Reticulum?
