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.
Many enzymes are incorporated into metabolic pathways. A metabolic pathway is a series of chemical reactions that transform one or more reagents into an end-product that's needed by the cell. The enzymes in a metabolic pathway--much like people passing a pail of water along a bucket brigade--move a reagent along until the end-product is produced.
