Metabolism is the set of life-sustaining chemical reactions in organisms. The three main purposes of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks for Proteins, lipids, nucleic acids, and some Carbohydrates; and the elimination of metabolic wastes. These Enzyme -catalyzed reactions allow organisms to grow and reproduce, maintain their structures, and respond to their environments.[from Wikipedia]
