When whole cells or large molecules in solution are engulfed by a cell, this endocytosis is specifically termed
A)pinocytosis.
B)phagocytosis.
C)facilitated transport.
D)facilitated diffusion.
E)exocytosis.

Question

Quizplus · Accepted Answer

Phagocytosis specifically refers to the engulfment of large particles or whole cells, while pinocytosis is the uptake of small fluid droplets. Facilitated transport and diffusion involve the movement of molecules across a membrane with the aid of protein channels or carriers, while exocytosis is the opposite of endocytosis - the secretion of molecules out of a cell. Therefore, option B is the correct choice for the given question.
