The metabolic process in which energy is liberated by the destruction of complex substances is known as catabolism. This process involves breaking down larger molecules into simpler ones, resulting in the release of energy that the body can utilize for various functions. For instance, during the catabolic process, nutrients such as carbohydrates, fats, and proteins are broken down, releasing energy stored within their chemical bonds. This energy is critical for maintaining basic physiological functions, powering cellular activities, and fueling physical activity.

Anabolism, in contrast, refers to the metabolic pathways that construct molecules from smaller units, which typically require energy input. Homeostasis signifies the body's ability to maintain a stable internal environment, while metabolism encompasses all chemical reactions in the body, including both catabolic and anabolic processes. Therefore, catabolism is specifically associated with energy release through the breakdown of complex substances.
