The process by which molecules move from areas of high concentration to areas of low concentration is called:
A) diffusion.
B) osmosis.
C) gating.
D) exocytosis.

Question

Quizplus · Accepted Answer

The process described in the question, in which molecules move from areas of high concentration to low concentration, is called diffusion. Osmosis refers specifically to the diffusion of water molecules across a membrane from an area of low solute concentration to an area of high solute concentration. Gating refers to the opening and closing of channels in cell membranes to allow specific molecules to pass through. Exocytosis is a process by which cells release molecules or particles by fusing a membrane-bound vesicle with the plasma membrane, allowing the contents to be released outside of the cell. Therefore, the correct answer is A) diffusion.
