A) Proteins in cell membranes can travel with in the lipid bilayer
B) Proteins can also undergo flip-flap movements in the lipid bilayer
C) Proteins can remain confined within certain domains of the membrane
D) Many proteins remain completely embedded within the lipid bilayer
Correct Answer: B
Solution :
There are many different proteins embedded in the membrane. Except for flip flop movements rest occurs. Choice (a) is amply demonstrated when the travelling proteins aggregate at sites of endocytosis. Choice (c) type of proteins can be enzymes which are confined to cetrain domains (for e.g., present only on cell surface) choice (d) types are non-trasmembrane proteins.You need to login to perform this action.
