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? What does is comprise of? Any metabolic reaction involving the transfer of electrons from an electron donor to an electron acceptor. Reactions when electrons are accepted are...
