What Is Cellular Metabolism?
Metabolism is the collection of reactions that take place within cells of an organism. These reactions that build up and tear down materials are going on constantly in each and every cell in your body. Anabolic reactions of metabolism (anabolism) build complex molecules from simple substances and typically require an input of energy in order to take place. Catabolic reactions, or catabolism, break down complex molecules into simpler ones often resulting in a release of energy. In the metabolic process, food molecules (most commonly glucose), are broken down in our cells and the energy released is transformed into ATP, the currency of cellular energy.
