Explanation

Metabolism is the sum of all chemical reactions in an organism, including both anabolic (constructive, building complex molecules) and catabolic (destructive, breaking down molecules) pathways. Catabolism only refers to breakdown reactions, while anabolism refers only to building reactions. Physiology is the broader study of how organisms function.
