Question

which of these describes a catabolic pathway? a pathway that breaks down molecules into smaller subunits a pathway that constructs molecules from smaller subunits a pathway that consumes energy a pathway that transmits a signal within a cell

Explanation:

Catabolic pathways involve the breakdown of larger molecules into smaller subunits, often releasing energy in the process. Anabolic pathways construct molecules from smaller subunits and usually consume energy. Signal - transmitting pathways are related to cell - signaling and not catabolism.

Answer:

a pathway that breaks down molecules into smaller subunits
