How Does Stuff Get Into Your Cells? (Cell Membranes): Crash Course Biology #24

The cell membrane is a protein-studded phospholipid bilayer that not only protects our cells, but also regulates what goes in and out. In this episode of Crash Course Biology, we’ll look at the structure of the bilayer, learn about its discovery, and explore the many ways substances can be transported into and out of cells.
Chapters:
Introduction to the Cell Membrane 00:00
Membrane Structure 2:10
Membrane Proteins 4:53
Membrane Transport 7:07
Review & Credits 11:54

i think the most important thing i learned from this episode is that dr. sammy would make an amazing dungeon master :P

[@Naafidy]

My A&P professor taught us the immune system using this exact analogy. Her name is Dr. Margaret Long, and she is an amazing instructor! It helped us to understand the immune system so well.

This was a really good episode!! My husband's been diabetic for a long time, and I just got diagnosed recently myself, so I've done quite a bit of reading about insulin - and this is the single clearest explanation I've ever come across!! In fact it actually explains why we have to take insulin by subcutaneous injection, too. I knew about some of the proteins and processes but the illustration of the mechanisms is just so well done here - they make SENSE in a way they didn't before, the various separate bits of information finally lining up into a coherent picture in my head.
Great job, y'all!!!

[@Arosukir6]

I am being murdered every episode by Dr. Sami's amazing DRAMATIC VOICE! 😍😂 Informative, funny, and so cool!

[@pedrostormrage]

11:18 An interesting consequence of those transporting processes is that exocytosis increases cell membrane surface area, while endocytosis decreases it. That implies there needs to be a balance between both, or the cell could become too big (potentially rupturing) or too small.

I have a request can you please make the serieses of physics chemistry and English too so we can easily get knowledge and benefits from this channel it is difficult to search best channel but randomly i found this channel on RUclips this really amazing 😍 love from Pakistan

[@andrearodriguez9005]

Yay!! New updated crash course vids for Biology 🥰

[@suhani551]

I am taking biology in college even tho i did not take it in high-school. thank you crash course for these informative videos!!

[@itsdamomma6028]

I ADORE this science guy!! Being an entomologist by education makes how he structures the lessons, what details get an extra nudge, such great discussion points! I was so nervous to try homeschooling my kid cuz finding lesson plans that give this kind of thoughtful, accurate info aren't so easy to find, let alone explain to a kid. Crash course and their professors are doing such excellent work- and my kid absolutely adores the bio lessons from this teacher 🤗

[@toothbrush752]

How do viruses trick the cells into letting them in? Also love the new biology vids it's definitely my favorite subject

[@Beryllahawk]

Proteins again! The viruses have proteins on their surfaces that can mimic "authorized" stuff; that tricks the transport protein, the gate, into opening.

[@TheGadecka]

I love this analogy of the cell wall

[@earthplanet403]

I love the structure of these series from really big biologic systems to now veryy small! Thankyou sm for these videos.

[@user-lj7gh7yv4y]

You are a new teacher. Your way of teaching is amazing

[@spicykneepain]

We love bio vids 🗣️

[@TenzinT]

I absolutely love this video and the way it simplifies complex biological concepts! 🌟 It would be amazing to see a follow-up video exploring the evolution of the cell membrane, particularly focusing on Abiogenesis. Understanding the origins and development of this crucial cellular structure would be incredibly fascinating! 🧬✨

[@malkum77ify]

I love molecular biology! That was my favorite subject.

[@siriendera506]

please continue this biology series...

[@stevenmiller2427]

That was outstanding.

[@ghulamqadirhattar2791]

First of all i wanna appreciate the whole team of crash course who brings alots of informative vedios regarding our subjects thankyou ❤ lots of love from Pakistan ❤ iam the biggest fan and student of this series and dr Sammy is doing his best his way of teaching is so amazing 😍 keep doing I know this platform become most famous in the whole world its pray from my side as Iam Muslim ❤ inshallah you'll become most popular by these series and this channel

[@EduardMedina-ri5fx]

Awesome thanks to this course i have an A on Biology is cool

[@gailaltschwager7377]

Thank you!

[@urbidas8893]

SO EARLY!! love the vid, 80th like!

[@aurorafauna4195]

I wanna play D&D now

[@user-kq3if6pc6f]

You have a watch in the video, Courageous!

[@monicareid8858]

Nice
Well done ☀️

[@DeathValleyDazed]

Sammy should be knighted by the Queen for this excellent video👑

[@irate_desperado8597]

I need to stop scrolling through my subscription while working out. Cant exercise the brain and the body 😅
