White blood cells engulf bacteria using ________.
A) phagocytosis
B) pinocytosis
C) osmosis
D) receptor-mediated exocytosis

Question

Quizplus · Accepted Answer

White blood cells engulf bacteria using phagocytosis, which involves the cell membrane extending around the bacteria to form a phagosome, which then fuses with a lysosome for degradation of the bacteria. Pinocytosis is a process by which cells take in fluid and solutes. Osmosis is the passive movement of water across a semi-permeable membrane. Receptor-mediated exocytosis is a way for cells to release molecules by specifically targeting receptors on the cell membrane.
