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.
In biochemistry, a metabolic pathway is a series of chemical reactions occurring within a cell. In a pathway, the initial chemical (metabolite) is modified by a sequence of chemical reactions.These reactions are catalyzed by enzymes, where the product of one enzyme acts as the substrate for the next. Some metabolic pathways flow in a 'cycle' wherein each component of the cycle is a substrate for the subsequent reaction in the cycle, such as in the Krebs Cycle (see below).
