    Metabolisms are all the chemical reactions that the living cells and organisms use to maintain life. It also divides into two categories: Catabolism – that breakdown the molecules to obtain energy and Anabolism – that creates all of the compounds that the cells need to function. Nutrition is an important part of the availability of nutrients that utilized in the reactions that either synthesize or catabolize the material that is employed by the cells to produce power. This power is a requirement
