Metabolic pathways

Metabolism is defined as the group of life-supporting, enzyme-mediated chemical reactions in organisms. A metabolic pathway is a set of these chemical reactions that involve anabolism (synthesis of complex biomolecules) and catabolism (breakdown of biomolecules into small molecules) that occur inside a cell. Metabolites are the reacting substances, products, and intermediate substances of an enzymatic process that are altered by a series of chemical events catalyzed by enzymes.
