When liquids or macromolecules are engulfed and moved into the cell, this kind of endocytosis is known as what?
Correct Answer
pinocytosis
Explanation
Pinocytosis (from the Greek for "cell drinking") is the process by which a cell engulfs liquids or dissolved macromolecules. The cell membrane folds inward around the liquid droplet to form a small vesicle. In contrast, phagocytosis ("cell eating") involves the engulfing of large solid particles such as bacteria.
