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]

ChemicalProcess |
A ChemicalProcess occurs whenever chemical compounds (CompoundSubstances) are formed or decomposed. For example, reactants disappear as chemical change occurs, and products appear as chemical change occurs. In a chemical change a chemical reaction takes place. Catalysts in a ChemicalProcess may speed up the reaction, but aren't themselves produced or consumed. Examples: rusting of iron and the decomposition of water, induced by an electric current, to gaseous hydrogen and gaseous oxygen.
