When whole cells or large molecules in solution are engulfed by a cell, this endocytosis is speciﬁcally termed ______.

Question

Quizplus · Accepted Answer

Phagocytosis is the process by which cells engulf large particles or cells, essentially "eating" them. This is distinct from pinocytosis, which involves the ingestion of liquid and small molecules, and from exocytosis, which is the process of expelling materials from a cell. Facilitated transport and facilitated diffusion involve the movement of molecules across cell membranes with the help of transport proteins, and do not involve engulfing materials.
