Briefly describe catabolism and anabolism


The breakdown of body compounds is known as catabolism. These reactions usually release energy. Glycogen can be broken down to glucose, triglycerides to fatty acids and glycerol, and protein to amino acids. When the body needs energy, it breaks any or all of the four basic units—glucose, fatty acids, glycerol, and amino acids—into even smaller units. When the body does not require energy, the end products of digestion (glucose, amino acids, glycerol, and fatty acids) are used to build body compounds in a process called anabolism. Anabolic reactions involve conversion of glucose to glycogen or fat, conversion of amino acids to body proteins or fat, and synthesis of body fat from glycerol and fatty acids. Catabolism and anabolism are examples of energy metabolism.
