    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 :)

    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?

  • @Hawkman6788
    @Hawkman6788 6 ปีที่แล้ว

    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!

  • @jenroberts7267
    @jenroberts7267 3 ปีที่แล้ว

    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?

  • @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
      @openworld1566 6 ปีที่แล้ว

      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

  • @faizamuhammadjawaid2828
    @faizamuhammadjawaid2828 7 ปีที่แล้ว

    Channel protein responsible for the moment of ions against the concentration gradient not down the concentration gradient.

    • @randomname4900
      @randomname4900 7 ปีที่แล้ว +1

      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.

    • @randomname4900
      @randomname4900 7 ปีที่แล้ว

      And cotransporters are channel proteins I think.

  • @hassandaud7149
    @hassandaud7149 4 ปีที่แล้ว

    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?
