the aggregate of chemical processes that constitute one of the aspects of metabolism in an organism and are directed at forming the components of cells and tissues. Anabolism is interrelated with the opposite process, catabolism, since the decomposed products of various compounds can be reused in anabolism, forming new substances in different combinations. Anabolic processes, occurring in green plants with the absorption of solar energy, are of planetary significance and play a decisive role in the synthesis of organic substances from inorganic ones.
