The Means by Which a Cell Transports Large Molecules Out

Question

The means by which a cell transports large molecules out of the cell is called
A) phagocytosis.
B) endocytosis.
C) exocytosis.
D) diffusion.
E) active transport.

Accepted Answer

Exocytosis is the process by which large molecules and particles are transported out of the cell. It involves the fusion of vesicles containing the molecules with the plasma membrane, and the subsequent release of the contents into the extracellular space. Phagocytosis is the process by which cells engulf and digest large particles, while endocytosis is the process by which cells internalize molecules from the extracellular environment. Diffusion and active transport are mechanisms for transporting small molecules across the plasma membrane, but they do not involve the movement of large molecules or particles.
