Janjay Spike . dont say horrible to your professor

[@vinayaksharma9518]

LOL😂😂😂

[@asiaaden1763]

And the horrible textbook they give you from the university library....

[@mariahnicole5332]

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!

[@livfrazier6295]

Makes so much sense now! Thank you.

[@Linkfan007]

PERFECT!!! this is exactly what I needed to know! Thank you!!!

[@zonishbaloch110]

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. :)

[@joyceli831]

love this video!!!!! it is extremely helpful for me to do my project about cell membrane proteins!!!

[@Rorry124]

I am sooo thankful for you it’s be much easier for me right now 💜

[@gultekinakay9632]

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 really helped me on my ap bio quiz!! thank you!!!

[@oldhag287]

Peripheral, integral, lipid bound, channel, carrier, glycoproteins(can be any of the previous ones)

[@neetuchawla9428]

Thanks for making this so easy to understand

[@JakaKeete]

Bra this really helped. God Bless you for blessing us with this video.

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 :)

[@shagufthahaider4911]

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

[@sarishmasari4718]

awesome thank you somuch

[@davidmansaray3563]

Great work!

[@mopaj8524]

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

[@ratojatamazight]

Thanks

[@muaaziqbal4699]

BEST ONE !

[@yvonneakuoko]

This X really amazing I am really enjoying this 😚😚

[@marymez3924]

You're the best ! Thankyou

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.

[@Rahafpeace]

My life saver

[@khadimhussainsapu601]

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....!!

[@phillipbaek41]

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?

[@rawandahhan8866]

Thank youu

[@mariandawood6765]

You are great teacher 👍🏼

[@anonymous-vd6zv]

thanx these videos are really helpful

[@solonaz2m670]

Thank you so much

[@LHEarb]

Please help us more in biology

[@hassandaud7149]

My bio sir told the same concepts🤗

[@logicmlotshwa5315]

THANX

[@naveenjolly1652]

Thank you 😭

[@samanthalau5482]

this guy is good

[@parulaggarwal9405]

These videos are much better than my Biology teacher....☺😊

[@husseinzuhair5377]

Thanx

[@zahidaahmad9389]

Thanks, best effort.

[@jojosy3943]

WooOOw very GOOD :)))

[@orlandoeatspudding]

what are some types/names of peripheral and integral proteins??

[@emmanuellaadobea7171]

Thanks for such an awesome video Dude you really make learning easy and fun💃💃

[@emmanuellaadobea7171]

🙏🙏💃💃💃

[@issafun3012]

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

[@ikramghz831]

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 😍😍😍😍

[@Santo-ob7kp]

khan academy my question is how the signaling glycoprotein communicate to each other?

[@tayo2810]

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

[@GRLVGD]

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

[@tayo2810]

+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.

[@mrstorrente]

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.

[@openworld1566]

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

[@SubhamMeher]

U are d best

[@haddadmj96]

Perfect thanks

[@veronicanoordzee6440]

Almost ;-)

[@taiyo4543]

You just saved me... THANK YOU 😭😭👌

[@nuhaalbeldawi415]

Wher is lipid anchored protein ? Thank you for this amazing video 😊😍

[@andresmendoza8213]

Glycoproteins are only found on the side of the extracellular matrix not in the cytosol.
