What is metabolism? Metabolism is all of the chemical reactions in an organism. What are the major classes of metabolic reaction? Catabolism: All of the decomposition reactions in an organism taken together. Anabolism: All of the synthesis reactions in an organism taken together. What is oxidation and recucition reaction?
