    Why are lipids and proteins free to move laterally in membranes?

    A) The interior of the membrane is filled with liquid water.

    B) There are no covalent bonds between lipid and protein in the membrane.

    C) Hydrophilic portions of the lipids are in the interior of the membrane.

    D) There are only weak hydrophobic interactions in the interior of the membrane.

    E) Molecules such as cellulose can pull them in various directions.



    C) Hydrophilic portions of the lipids are in the interior of the membrane.

    Feldman, I think "C" is wrong.. "D" makes more sense to me (someone correct me if I'm wrong).. The phospholipid-bilayer of membranes consists of hydrophilic heads on each exterior side and hydrophobic tails facing each other on the interior.. Therefore "D" would make more sense to me.


    yes i agree with you. D is the only answer that makes sense
