Question

which of the statements correctly contrasts anabolic and catabolic pathways? anabolic pathways use oxygen, whereas catabolic pathways do not use oxygen. anabolic pathways release energy, whereas catabolic pathways require energy. there is no contrast. anabolic and catabolic are synonymous terms. anabolic pathways are synthesis pathways, whereas catabolic pathways are degradation pathways.

Explanation:

Anabolic pathways build complex molecules from simpler ones (synthesis), consuming energy. Catabolic pathways break down complex molecules into simpler ones (degradation), releasing energy. Oxygen usage is not a defining contrast between them.

Answer:

Anabolic pathways are synthesis pathways, whereas catabolic pathways are degradation pathways.
