The release of intracellular materials by a vesicle at the cell surface is called
A) osmosis.
B) active transport.
C) exocytosis.
D) endocytosis.
E) an ion exchange pump.

Question

Quizplus · Accepted Answer

Exocytosis is the process of releasing intracellular materials by a vesicle at the cell surface. Osmosis is the movement of water molecules across a selectively permeable membrane, and active transport refers to the movement of molecules against their concentration gradient with the help of energy. Endocytosis is the process of taking in materials by the cell through the formation of a vesicle, while an ion exchange pump is a type of active transport protein that maintains the balance of ions inside and outside the cell.
