Cell membranes are structures of contradictions. These oily films are hundreds of times thinner than a strand of spider silk, yet strong enough to protect the delicate contents of life: the cell’s watery cytoplasm, genetic material, organelles, and all the molecules it needs to survive. How does the membrane work, and where does that strength come from? Nazzy Pakpour investigates.

This 5 minutes video sums up my 3 days effort of studying this topic in Biology AS level.
Same
this is the easier stuff in the topic
Kevin Salim Then your efforts are wasted, and you should focus better.
Kevin Salim I studied it for an entire bimester
Kevin Salim Me too. I'm not ready for second year.
Two weeks of 10th grade biology condensed into a 5 minute video and nothing is lost. Truly Ted-Ed is the ideal of education.
What I learned today:
TED-Ed has a collection of animated GIFs on Tumblr
Cyan Stickmin hahahha
Cyan Stickmin everyday you learn something new . #keeplearning.
Cyan Stickmin f
you must be a teenager, they think they know everything....
Their marketing is effective. :P
I'm in biology and we are learning this now. I'm glad I watched this. Thanks so much!!
serious, we had to learn it in 9th grade
Huh what is 9th grade!?!?!
@@maropepo9728 freshman year of high school
Amazing animation. The animation team deserves an applause.
Waiting for all those "the mitochondria is the powerhouse of the cell" comments😂
D.A.B Science and More! But do you know they use Blue and Red spectrum rather than green :v
The Mitochondria is the powerhouse of the cell
damn i remember that joke
yo lets give a shoutout to the endoplasmic riticulum. noone ever talk about him.
awesome protein synthesizer
This video is incredible! The animation and the narration together explains everything so clearly.
What did the cell say to his sister when she stepped on his foot? Mitosis.
I'll leave.
HAHAHAHAHAHAHA I APPRECIATE UR JOKE DUDE
IM DEAD XD
this is so goooooooooood lmao
Even though I'm seen this many times
it's still funny like the first time
👏👏
A 4~5min Ted-Ed video is worth 1 whole entire day in school :D
The powerhouse is the mitochondria of the cell.
You wrong it got

"Who knew cell membranes could be so complicated?!"
Super useful as a concise way to understand cell membranes! Helped me keep my studying focused.
Perfect timing for our cell assment! Thank you!
This is super helpful! Thanks a lot 🙏🏻 the animation is so great, I wasn’t understanding a thing from my textbook but here it is all clear!! Once again thank you 🙏🏻😇
I know exactly what cell membranes are yet I'm still here, what am I doing with my life right now?
Bukan Hamid we all do. Still interestingto watch tho
Whoa I luv code geass
Me too

This is helping me so much with my Science test! Thank you to TED-Ed, a special shoutout.
Bro... The youtuber is supposed to give YOU the shoutout... not you... :/
@@jonghyunan117 I forgot I even wrote this lmao. I was a pesky little kid who had no idea how to comment.
@@srijanampally LMAOO
Thanks for helping me TED, I have school tomorrow. And are any of you going to watch the eclipse? Comment if you are :)
Small Land Burrito Yes
I came here to solve my confused mind but the title says, "Cell membranes are way more COMPLICATED than you think"
but now with TED-Ed, I am super clear about things. thanks to this channel and information sharing lady/gentleman
now I really want to become a cell so that I can feel how its like.
cool cool.
yee
This has helped me a lot . Excellent job Ted ed
all these CELLs, but you still feel lonely.
all these CELL phones, but you still cant call me
all these CELLular networks, but you still cant connect with me
all these mitochondiras, but you still dont have power
all these CELLs, but you still couldn't charge me
stop with the shameless advertisements
Maybe your membrane is too thick
Something i couldn't breach
I tried to charge in
You soaked me out
You recognized me as a virus
Well, i'm a toxin afterall
Tell Me This I
Cell Movie XD
all these CELLs but I still can't beat Goku
I have never been this early to learn new stuff. Nothing can possibly top this moment.
I love TED ED a lot. The Animation is awesome!
This actually makes me excited to go back to college and do my a levels next year.
4:53 "And as always, thanks for watching"
MICHAEL, ARE YOU THERE???
Good animation! I have to rewatch, so it would get into my head.
This greater symmetry formation can be seen in the imperfect broken symmetry of cell life with positive and negative charge being relative to the membrane of each living cell.
I wish I had videos like this when I studied biology in high school.
Thanks for doing what you do TED...
Thanks a bunch...it was a big help for my lessons...
So good. Going to show this to my class!
Thanks for the video, its really helpfully for Biology classes.
What do cells use to communicate to each other?
CELL phones!
good one
reported for dad joke
J
BOOO. GET OFF THE STAGE!
Dad? Is that you?
Ojalá este recurso hubiera estado presente cuando estudié Biología en 1994 ... ! 😃 genial!
I love biology!
By saying "I love biology" you mean that you like to work on projects hours on end, meticulously research and collect data about how things work, cope with sleep loss just to do research....
Or
You just like to watch these fascinatingly animated videos on biology?
NKD second option 😅
Siddharth Pareek Chemistry, right? I'm currently reading a Campbell and cells are listed in the chemistry part.
why ? why do you have my name ?
Siddharth Pareek it is biology dummy
WoW! Amazing video 👏 In fact, I am an Indian and we are learning this chapter right now in our AS Level Biology and this video is so darn helpful for me and friends. Even our teacher loved it! Thanks a lot TedEd for these amazing videos! 😃👍
It's so amazing that humanity has all this knowledge
Where was this video when I needed it taking biology back in high school Dx
typing fast can cause accidents; you wrote the D before the x
you: Dx
plz somebody call an ambulance here, there is an injured emoji lying down in the comments, the body is lying here for about 3 years (your comment is that old )
Should've watched this before my bio exam HAHA
Please make a video on Bond angles also.
Great . tell us more about diffusion and osmosis in cell membrane
Wow a ted-ed video that I actually know more than 90% of what's being talked about
You should make a video about why we shouldn't look at solar eclipse
Great work by the way keep it up 💪🏼
Remember me before I am lost in the sea of comments
Gabriel Kerman okay
Gabriel Kerman
No! That's no way for a kerbal to die!
*adds a crazy amount of rocket boosters to your ship*
Much better!
No! Jack! Don't let go, Jack! Don't let go!
*_Gabriel Kerman_* P
I remember you
That's what I have read yesterday in a book and today you publish a video about it :D
When you have Ted ed questions to answer after the video and it’s due at 11:59 pm and you’re blasting because it’s 11:50
Please make a video about fotosynteses. Your channel is great!
*Photosynthesis
That's it. Thanks! My english is sucks, especially by writing
Qué bonitas ilustraciones. 💕
Cell menbrane are still more complicated than this when you start to study the numbers of proteins existent in different types of cells in especific tissues. Not to mention the video didn't exposured 5% of types of communication between cells (protein G receptors, MHC receptors,...)
TED explains better than any of my teachers In one go.
I saw the Total Solar Eclipse today in Gallatin, Tennessee, USA and now I want to tell everybody!
Such a brillant story told in such a lovely way - and then: so many mistakes in the animations...makes me cry, really!
Please can you guys make a video about the Van de Graaf Generator
There was a cool animation and a narrator in the ad before this and I thought I was watching the actual video and was confused to why it wasn't about cells
Her voice is so soothing.
So i wonder how water could be exchanged throgh this fluid mosaic as a polarized molecule? I know it doess not cross through the channel proteins so is it through the phospholipid layer..if its a yes how? Because according to what you said polarized molecules cant go throgh the phospholipi layer ...and how a cell can maintain its osmolarity bythe way?
I happen to have an exam about this tomorrow😂
Thanks TEDEd😘
please upload a riddle !
Nah, I always knew I knew nothing about them. It's complicated.
3:00 mark they seem to have placed water, a polar molecule, next to the charged molecule label (and I'm guessing a salt next to the polar label?).
Of course, the illustrator may have intended some other, less well-known molecule that just happens to look like water.
Where was this video last year when I had AP Bio?😂
Awesome. Wish you talked more about neurons but thats just because thats what interests me. Keep up the good work!
ScienceAIR PhD student in cognitive neurosciene
This was in my studies and an important part of my subject . I could understand better. Excellent job Ted Ed
Thank you TH-cam for recommending me this video right after my Biology test.
Engaging and at a good level for high school to intro college, but has a few issues: 1) the model implies that the fatty acid tails of the phospholipids are covalently bonded to each other across the membrane interior (nope); 2) the narrator talks about cells communicating through sharing "chemicals and proteins" - chemicals is a generic word, and may confuse the viewer about proteins (and water, phospholipids, Na+, etc.) being chemicals; 3) the model shows three different solutes going through the same transmembrane protein in the same direction. Channel and carrier proteins are very specific as to which solutes they allow across the membrane (most commonly, only one per type of carrier or channel), and to my knowledge only two-different-solutes cotransporters (same direction) have been found to date. Just 'cuz I teach this stuff.
But, is it possible to create a controlable bacteria to break through the cell membrane and dissolve lipid or the cholesterol ( just in case our body has too many of it ) ? Lets discuss
Rly nice animations recently !
I have a video idea. Where did the idea of last names come from?
Yes that's a great idea! Ted-ED, ARE YOU LISTENING?
This is very fantastic
2:37 Yeaheaheaaaah! Biochemistry! It's so damn cool QuQ
It is amazing how such thin membrane could protect a small object
good job!
Can some one explain how peripheral proteins anchor cell?
Amazing Thanks
But what happens to a cell's structure if the environments inside and out of it became non polar?
Good review of our sentences
Im a 1st year high and i sub because its our homework today yesssss
What a spectacular design.
Ah..i wish this was released last June bc biology just didn't make any sense inside my mind...so i failed my final test:((( this makes so much sense now lol thank u for this animation!!!!!!!!!!!
Amazing!!!
Good explain
How can I use this info to clear up my acne? 😐
Cell Membranes? Why would I watch that?
*TED IS MY TEACHER, I AM NOT ASHAMED*
thanks Ms. Duncan
Anyone else watch these videos at home more than at school?
The fact that this showed up in my recommended can only mean that my bio teacher has prescribed me too many bozemans.
Enderpearls at 4:27 😂😂😂😂😂
Thank you so much
I have a topic on this for our exams tomorrow, and TED Ed just posted this. WTF
Question. Can a cell survive good even if there is not an aqueus environment outside the cell ?
Yes look at your skin it's made up of cells can your skin survive dry?
Cell membrane width is 70-100angstrom unit
OMG I think she just breaks my mind by talking when the end music is playing...
Great design.
Cells are amazing!
5M people just subscribed to look smart, while only 1000 people actually subscribed for the videos
It’s pathetic
great clip :)
Wow I watched the video so soon this time
So is cell membranes aka fluid mosaic solid? Or liquid?
This rings a bell, I think I knew this once...🤓
Aren't the positively charged lipids facing outward? (not inward as here)
