Question

The process of __________ occurs when molecules move down a concentration gradient due to random molecular motion.

Answer 1

Diffusion is the process where molecules move down a concentration gradient due to random molecular motion. It occurs when molecules move from an area of higher concentration to an area of lower concentration. This natural process does not require energy and is responsible for the movement of substances, such as gases and small uncharged molecules, into and out of cells.
