Catabolism

Meaning

Catabolism represents the complex set of metabolic pathways in human physiology that involve the breakdown of larger, more intricate molecules into smaller, simpler ones. This fundamental biological process is essential for extracting chemical energy, which is then utilized to fuel various cellular activities and maintain homeostatic balance. The catabolic state is intrinsically linked to hormonal signaling, with hormones like cortisol and glucagon promoting the breakdown of stored resources such as glycogen, fat, and protein.
