Question

1. ____ occurs when the cell membrane surrounds and engulfs large particles, such as white blood cells engulfing bacteria.

○ exocytosis
○ phagocytosis
○ pinocytosis
○ receptor - mediated endocytosis

Explanation:

Exocytosis is the process of vesicles fusing with the plasma membrane and releasing their contents outside the cell. Phagocytosis is when the cell membrane surrounds and engulfs large particles (like bacteria by white - blood cells). Pinocytosis is the engulfing of liquid particles. Receptor - mediated endocytosis is a more specific form of endocytosis that involves receptors on the cell membrane.

Answer:

Phagocytosis
