Which term describes the breakdown of complex molecules into simpler ones, releasing energy?

Catabolism refers to breaking down complex molecules into simpler ones and releasing energy in the process. This energy is captured in carriers like ATP and NADH, powering cellular activities. In contrast, anabolism builds up larger molecules and consumes energy, while metabolism is the overall set of all chemical reactions in the cell, including both catabolic and anabolic processes. Fermentation is a specific anaerobic catabolic pathway, not the general description, so the broad and correct term for this breakdown-and-energy-release idea is catabolism.
