Question
The process by which a cell secretes macro-molecules through fusion of transport vesicle to the plasma membrane is called ___________.
Options:
A .  Exocytosis
B .  Endocytosis
C .  Pinocytosis
D .   Phagocytosis
Answer: Option A
:
A
The movement of macromolecules such as proteins or polysaccharides into or out of the cell is calledbulk transport. There are two types of bulk transport,exocytosisandendocytosis, and both require the expenditure of energy (ATP). Inexocytosis, materials areexportedout of the cell via secretory vesicles. In this process, the Golgi complex packages macromolecules into transport vesicles that travel to and fuse with the plasma membrane.
