The Digestive System and Body Metabolism

The Digestive System and Body Metabolism. Metabolism. Chemical reactions necessary to maintain life Catabolism—substances are broken down to simpler substances; energy is released Anabolism—larger molecules are built from smaller ones. Carbohydrate Metabolism.
