Metabolism is derived from the Greek μεταβολή ("metabolē") meaning "Change" is a group of chemical reactions that occur in living cells to sustain life. The three main objectives of metabolism are the conversion of food and fuel into energy for cellular processes. The conversion of food and fuel into subunits of proteins, lipids, nucleic acids and some carbohydrates. and nitrogen removal These reactions have enzymes as catalysts. for living things to grow and reproduce maintain structure and respond to the environment "Metabolism" can also refer to The sum of all chemical reactions occurring in living organisms. including digestion and transport of matter into cells and between cells These reactions are known as Intermediate metabolism (intermediary or intermediate metabolism) Normally, metabolism can be divided into two types: catabolism, which is the breakdown of large molecules into smaller molecules. The breakdown of organic matter, for example, the breakdown of glucose into pyruvate. to obtain energy for cellular respiration and anabolism (anabolism), which refers to the creation or synthesis of small molecules into large molecules in metabolism such as creating cell components Proteins and nucleic acids. The majority of catabolism is the release of energy. As for anabolism, energy is used for the reaction. Metabolic chemical reactions are organized in a metabolic pathway in which a specific chemical is transformed in a number of steps.
