Question

a metabolic pathway that releases energy by breaking down complex molecules to simpler molecules is what type of reaction? scientific molecular catabolic anabolic

Explanation:

In biology, catabolic reactions break down complex molecules (like glucose) into simpler ones (such as carbon dioxide and water). This process releases energy (for example, in the form of ATP during cellular respiration). Anabolic reactions are the opposite—they build complex molecules from simpler ones and require energy input. "Scientific" and "Molecular" are too broad terms and do not specifically describe this energy - releasing, breakdown reaction type.

Answer:

C. Catabolic
