Question

1. The type of motion least common in biological membranes is flip flop of phosphoplipid from one monolayer to the other. However, this does happen as part which of the following processes

a. binding to a receptor by a ligand

b. glycosylation of newly synthesized proteins

c. transfer of proteins to the golgi apparatus

d. membrane fusion during secretion

e. formation of coated vesicles

2. The type of motion least common in biological membranes is flip flop of phospholipid from one side of the bilayer to the other. However this does happen as part of which of the following processes

a. binding to a receptor by a ligand

b. formation of N-linked oligosaccharides

c. transfer of proteins to the golgi apparatus

d. membrane fusion during secretion

e. formation of coated vesicles

Explanation / Answer

1). e. formation of coated vesicles

Flippases are the proteins that perform translocation of membrane proteins from one side of a membrane to the other side, this is done by vesicle formation.
