Structure of adenosine triphosphate (ATP), a central intermediate in energy metabolism. Metabolism (from Greek: Î¼ÎµÏÎ±Î²Î¿Î»Î® metabolÄ, change) is the set of life-sustaining chemical transformations within the cells of living organisms.
Metabolism is the set of chemical rections that occur in a cell, which enable it to keep living, growing and dividing. Metabolic processes are usually classified as: 1  catabolism-obtaining energy and reducing power from nutrients. 2  anabolism-production of new cell components, usually through processes that require energy and reducing power obtained from nutrient catabolism.
