Realllyyyyy helped me to understand the topic ...thankyouuuuu soooooooo soooooo muchhh! At first when i saw people thanking i thought they are just random but when i listened i realized .. that itsss very helpfull
This video was so helpful.Thank you much! i have been struggling with this topic so much and mixing functions of all the these proteins but your very organised video cleared away all the doubts. :)
I finally understood this. After watching 100000000 other videos on this by different people, your video actually helped me understand this all. Thank you so much! I feel more confident for my test on Saturday :)
Dammnn his method of explanation is so smooth and understanding. Every word he says just just gets in my head within seconds! He's truly my carrier protein. haha
Excellent lectures, thank you! Anyone knows the software and hardware they are using to write on the screen and prepare these lectures? It is a very effective software I want to adopt it.
Khanacademy saves our lives from boring and stupid professors/ teachers. THANK YOU Mr. Salman Khan.. Without ur help Me and Many others would have done worse in our Exams.
wavv ... first of all I wana say thank you soo much sir from ma core of heart for teach us a topic in such an outstanding... I wish u were in our college....!!
Wait, in my textbook, it says that are are passive transport proteins (no ATP) and active transport protein (uses ATP), so is the passive transport protein basically channel protein and active transport protein carrier protein?
what is it protecting it from 530 pls. do carrier protiens use atp going both ways, or just one and how do they not use atp and when do they not use atp. i am curious
would really like to advise u one thing, always give a significance/ importance of each and everything you are presenting in the vedio. like..what is the significance of lipid bound protein, why it is present there, theremust be some reason
Integral membrane proteins are not always integrated throughout the entire membrane. There are 2 classes of integral membrane proteins a) Monotopic and b) Polytopic. Monotopic only interact with one side of the leaflet(one side of the phospholipid bilayer). Polytopic integral membrane proteins are ones that pass the entire phospholipid bilayer like the one you drew. Thanks!
Great video! My understanding, though, is that glycoproteins do not exist on the cytosol side of the cell membrane. However, there are glycosyltransferases that are on the membrane inside the cell. Is this right?
you should have talked about how to remove peripheral, integral, and GPI proteins from the membrane like using detergents or increasing ionic strength, etc.
Hey, amazing video. Explained it better than my lecturers. I'm trying to understand the GPI Anchor in a basic sense but cannot get my head around it. Would it be possible to give a brief description of what it is and how it works please? Thanks in advance! x
Wouldn't the carbohydrates (glycoproteins) only be located on the outer surface of the cell? I noticed you drew them on both leaves of the membrane. Thank you.
Yes I thought the same thing, I think carbonhydrates only appear on the outher surface of the membrane because they function as signalling proteins, so it would make no sense if they were located also at the interior side of the membrane, since there are no cells to interact with at this side
No. Channel proteins facilitate ONLY passive diffusion for specific substances such as ions, and other relatively large polar molecules. This makes sense because most, or maybe (all), of the time, channel proteins have a hollow tube-like structure which allows the passage of different substances down their respective concentration gradient. BUT (though I'm not very sure), other transport proteins such as cotransporters use the indirect pass of energy(ATP), which is the potential energy released when molecules such as ions move down their concentration gradient, by a nearby active transport pump to allow the passage of certain molecules against their concetration gradient.
Great video!!! But I don't think carbonhydrates are also located at the interior side of the membrane, or am I wrong? It wouldn't make sense to locate carbonhydrates on this side, since there are no cells to interact with
If the carrier proteins towards the conc. Gradient then it is facilitated diffusion If the carrier proteins move substances against the conc. Gradient then it is active transport.... Am i correct?
Good day! May I ask what type of integral membrane protein functions as pathway of ions for diffusion? How about the type of intergral membrane protein pulls molecules into the cell? Thank you
It's very easy to understand just because of the way you are teaching. Thank you..
Realllyyyyy helped me to understand the topic ...thankyouuuuu soooooooo soooooo muchhh! At first when i saw people thanking i thought they are just random but when i listened i realized .. that itsss very helpfull
Thank you! This has been the one topic on cells I’ve struggled with and this video is amazing! Hoping to ace my test tonight!
teach 500% better than my horrible professor
+Janjay Spike Same!
Luna Rumba Tamang
Janjay Spike .
dont say horrible to your professor
LOL😂😂😂
And the horrible textbook they give you from the university library....
what a video ...... this whole youtube channel is just out of the world
Peripheral, integral, lipid bound, channel, carrier, glycoproteins(can be any of the previous ones)
This video was so helpful.Thank you much! i have been struggling with this topic so much and mixing functions of all the these proteins but your very organised video cleared away all the doubts. :)

He's truly my carrier protein. haha
Awesome, thank you very much.
Thank u so much....this really helped me to understand about carrier and channel proteins for my exam 2moro❣❣❣🤙🤙🌸🌸
PERFECT!!! this is exactly what I needed to know! Thank you!!!
YASSSS HIT ME WITH DAT CLEAR EXPLANATIONS!!!
it all makes sense now!! thank you :)
Excellent lectures, thank you! Anyone knows the software and hardware they are using to write on the screen and prepare these lectures? It is a very effective software I want to adopt it.
You are great teacher 👍🏼
You're a real humane being!
Thanks for making this so easy to understand

Thanks for such an awesome video
Dude you really make learning easy and fun💃💃
🙏🙏💃💃💃
wavv ... first of all I wana say thank you soo much sir from ma core of heart for teach us a topic in such an outstanding... I wish u were in our college....!!
This X really amazing I am really enjoying this 😚😚
This video was elite Thank you very much
These videos are super helpful for my advanced biology 11 class
MASHA ALLAH excellent class, hoping for more videos
awesome video!!
I wish I found these videos when they came out. I'd probably be a medical doctor by now lol
Thank you so much!
My bio sir told the same concepts🤗
Bra this really helped. God Bless you for blessing us with this video.
Wow so easy to understand thank you
you really helped me on my ap bio quiz!! thank you!!!
Wait, in my textbook, it says that are are passive transport proteins (no ATP) and active transport protein (uses ATP), so is the passive transport protein basically channel protein and active transport protein carrier protein?
Thanks ,I now get it.
thanks a lot
These videos are much better than my Biology teacher....☺😊
Makes so much sense now! Thank you.
khan academy my question is how the signaling glycoprotein communicate to each other?
Easy to catch and understand
You're the best ! Thankyou
C'est encroyable!!
Glycoproteins are only found on the side of the extracellular matrix not in the cytosol.
Very helpful thx!
I am sooo thankful for you it’s be much easier for me right now 💜
I'm really grateful for you , god bless you♥️
love this video!!!!! it is extremely helpful for me to do my project about cell membrane proteins!!!
what are some types/names of peripheral and integral proteins??
what is it protecting it from 530 pls. do carrier protiens use atp going both ways, or just one and how do they not use atp and when do they not use atp. i am curious
would really like to advise u one thing, always give a significance/ importance of each and everything you are presenting in the vedio. like..what is the significance of lipid bound protein, why it is present there, theremust be some reason
+Gurveen Chawla captain here, hope im not to late. Its used to strengthen the wall and make it more durable. Im not sure what else though.
Thank you sir 🙏
Thanks very very helpful
OMG! Thank youu so much. It helped me to understand my studies, i have BAC and i think this will help me in my exam 😍😍😍😍

You solve my confusion
Thank you much love

Very well demonstrated! 👌👌♥️
you're great! thank you so much
That was really helpful and very clear!

Thank you so much, it’s really helps !
i speak arab and study in franch and learn in english that's beceause how you explain
thank you
thank you so much for these videos! Extremely helpful :)
Which grade?

Thank you! Really useful.
Great work!
JazakAllah
amazing video! thank you so much
this was really good thanks
Thank you 😭
😍😍😍 thank yooou
just wow
Excellent explanation!
awesome thank you somuch
thank alot great effort ......................
thanx
these videos are really helpful
You just saved me... THANK YOU 😭😭👌
Are channel proteins and carrier proteins also integral proteins?
3:15
I wish you were my bio teacher :(
thank you
thanks dude!
Please help us more in biology
one thing was wrong, the carbohydrates are found only on the outer monolayer of membrane, not in the cytoplasmic site of membrane
whats the software used here?
this guy is good
Thanx
Nice video . Well explanation.👍
How can I get your other microbiology videos
Wher is lipid anchored protein ?
Thank you for this amazing video 😊😍
Channel protein responsible for the moment of ions against the concentration gradient not down the concentration gradient.
No. Channel proteins facilitate ONLY passive diffusion for specific substances such as ions, and other relatively large polar molecules. This makes sense because most, or maybe (all), of the time, channel proteins have a hollow tube-like structure which allows the passage of different substances down their respective concentration gradient. BUT (though I'm not very sure), other transport proteins such as cotransporters use the indirect pass of energy(ATP), which is the potential energy released when molecules such as ions move down their concentration gradient, by a nearby active transport pump to allow the passage of certain molecules against their concetration gradient.
And cotransporters are channel proteins I think.
Thank youu
Great video!!! But I don't think carbonhydrates are also located at the interior side of the membrane, or am I wrong? It wouldn't make sense to locate carbonhydrates on this side, since there are no cells to interact with
My life saver
Thanks, best effort.
If the carrier proteins towards the conc. Gradient then it is facilitated diffusion
If the carrier proteins move substances against the conc. Gradient then it is active transport....
Am i correct?
you are genius !
Thank you a lot :)
Good day! May I ask what type of integral membrane protein functions as pathway of ions for diffusion? How about the type of intergral membrane protein pulls molecules into the cell? Thank you
Not even in my native language, and i understood better
