  • 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

    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!!!

    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.

    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 UA-cam this really amazing 😍 love from Pakistan

    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 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 🤗

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

    • @Beryllahawk
      @Beryllahawk 5 місяців тому +7

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

    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! 🧬✨
