Question

a(n) __ reaction creates bonds between substrate units; a(n) __ reaction breaks down bonds between substrate units.
o catabolic; enzymatic
o anabolic; enzymatic
o anabolic; catabolic
o analog; monologue
o catabolic; anabolic

Explanation:

Anabolic reactions build complex molecules from simpler ones by creating bonds between substrate units. Catabolic reactions break down complex molecules into simpler ones by breaking bonds between substrate units. Enzymatic just refers to reactions involving enzymes and is not the best - fit for the description. Analog and monologue are not relevant in this biochemical context.

Answer:

C. anabolic; catabolic
