The capacity of the plasma membrane to fuse with or engulf particulate matter and then pinch off and move out of the cell is known as what?
Correct Answer
exocytosis
Explanation
Exocytosis is the process by which the plasma membrane fuses with a vesicle and expels its contents outside the cell. The reverse process — engulfing material and bringing it into the cell — is endocytosis. Exocytosis is used to secrete hormones, digestive enzymes, and other substances from cells.
