    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 :)

  • @phillipbaek41
    @phillipbaek41 7 років тому +2

    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?

    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!

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

  • @mrstorrente
    @mrstorrente 7 років тому +5

    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 5 років тому

      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

    @jenroberts7267 2 роки тому

    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?

    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....
