White blood cells engulf bacteria by means of __________.
A) phagocytosis
B) cotransport
C) pinocytosis
D) active transport
E) receptor-mediated endocytosis

Question

Quizplus · Accepted Answer

White blood cells use phagocytosis to engulf and destroy bacteria. Phagocytosis is a process of engulfing large particles or entire cells by surrounding them with a portion of the cell membrane, which forms a vacuole called a phagosome. The phagosome fuses with lysosomes, and the contents are digested by lysosomal enzymes. Cotransport, pinocytosis, active transport, and receptor-mediated endocytosis are not involved in bacterial engulfment by white blood cells.
