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
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 ?
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!
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
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 :)
'perhaps an even better name for a band' haha cutest thing I've ever heard ;)
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!
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!
wow I never knew that cytoplasm is everything in the cell ;___;
Me too
Except the nucleus
شكرا جزيلا
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.
4:14 The relevant part in accordance to the title.
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!
Mr. Khan., thanks for yet another great illustrative video.
after watching this video twice, i now possess great intellectual capacities. i can cause natural disasters by sneezing.
Really kind description about Golgi apparatus. Thank you for this video.
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.
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!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
east and west khan academy is the best
Man i could swallow all the lectures given by him ! Now i love Biology !
I love how you explain this lesson. This helped me understand the process😄
so it's effectively a quadruple lipid layer?
Now that I think of it ENDOPLASMIC RETICULUM is actually a really good name for a Band😂😂👍👍
Nisa_Tandon Bands a-make him dance..
you sound like Kronk from Emperor's New Groove and it helped me get this so thanks lol
thanks so much! Watched it 2 times, I understand it now.
Keep doing what you're doing, really helpful. I have a confusing teacher.
Thank you so much.
Very hood video, thank you! Finally I understood how ER work, and why.
So simple yet so complicated
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!
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.
You're such a bless to humanity !
Why are you not teaching my class!!! This makes so much more sense then how my professor explained it... Thanks you!!!!!
Thank you so much! Always informative and accurate!
Extremely clear and concise thank you!!!!!!
students can understand 100 percent concept, by watching your video
Wow.....I used to think cytosol and cytoplasm are the same thing.
Sal...you Rock 🔥🔥🔥🔥🔥
thank you brother that was useful
finally understood why some proteins are translated in cytoplasm and some in ER! :D
7:01 in this time ur laughing 🤣
thank you
When you put it on x2 it sounds like he repeats the phrase 10 times. Or x0.25.
THANK YOU & PEACE
The sir like a week and like after disease 😒😑 but enthusiastic
Ur lecture make this topic so easy
thank you very much.
is there any benefit from connection between perinuclear space and lumen of endoplasmic reticulum?
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
Ximena Leyva Peralta
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).
really useful for my studies. Thank you !
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
i can't believe i found the videos my high school teacher showed us. He wouldn't even teach, just show this freaking videos
It is wrong to say that the protein is synthesized in the ER. It should be made clear that only specific ones are going there, the ones which have specifiek signal sequence for it. Some protein are synthesized in the
cytosol.
Proteins wich have specifiek signal sequence are synthesized in ER.
This is beautiful. Thank you Khan!
All on a sudden biology had become fearful and boringstuff for me.Thnx for making me enjoy it again.
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.
very good for me! tks u so much
Is it a bilipid layer or lipid bilayer? If bilipid, what are the two lipids? "Bilipid layer" yields nothing in a search.
nice veido, and detialed explanation. But dont be nervous, you can do better!
I think there's a story behind why you are laughing when mentioning ER as band name🤣
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 😂
Great sir thanks
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)
The best you are, Khan academy.
Thank you! This video really helped.
Thank you !😍
better than my lecturer :) thanks for the video. (y)
You are a grade-saver, sir
My Kids can learn from you
Hmm did u missed the point that the protein that join the golgi body carbohydrate is added to form glycoprotein ?
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)
Sir khAn your voice is awesome👌👌👌👌👌
Anyone else regretting signing up for the SAT subject test after having not taken for biology for three years? meeeeeeeee
Rachel Delaney I’m with you too 💁🏾♀️ We got this
everthing was explained amazingly but i got a question .....what is cytogel?
If you want to know what Cytogel is, its a company. But I'm pretty sure it's Cytosol but he might have said cytogel in the video. Cytosol is, in short, a water based solution that contains ions, small molecules, and macro molecules. It is a place where a lot of metabolic reactions take place.
@@rudra8293 thanks i had studied about cytogel that its a part of cytoplasm and so is cytosol and i was told that cytgel is the near the nucleus part the one with lots of thickness
THIS IS GREAT!
Omg golgi hma matag very nice explanation
Actually..i have a confusion ..golgi is also formed from the budding of SER and also modify the proteins coming from ER..?
Thank you, so helpful
watch on 1.25x
These vids are great!
I wish i would be compatible to your pronounciation
wowsers this is awesome
Insaene in the Memebraene!!
Yes! Yes! Yes!
Nucleus doesn't have double membrane it's one membrane with two parts
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?
And on the 8th day, god created Sal Khan.
Understood everything
so... did you make a band named Endoplasmic Reticulum?
Can i study from this to the emsat exam?
I feel like in the entire video, all I got is "let me just draw....."
ok watching this in 2019 and I have a question-- so how is the protein processed and "matured" when mRNA attaches itself to a free-floating ribosome instead of one that's attached to an E.R.?
That's because of the mRNA. mRNA destined for the ER begins with what's called a signal peptide. As soon as that's translated a protein called SRP binds to it and then binds to the ER. The signal peptide is later cut off from the peptide string.
A bit late but that is the gist of it.
Thank you so much this helped so much
The dutch subtitles were even more helpful XD
good
Thank You
Thanks a ton
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
Why cell synthesise protein when we can have it by food?
