Metabolism : the chemical reactions that occur in a cell Catabolism : complex Rx are broken down into smaller ones (release energy) Anabolism: Rx that uses energy to assemble more complex molecule. Amphibolic pathways: pathways that are either anabolic or catabolic * Each Rx are catalyzed by a different enzyme Endergonic: energy consuming Exergonic: release energy Aerobic: presence of O2 Anaerobic: without O2 Energy : the ability to do work G: free energy; the energy in a system that is capable of doing work. ΔG: G products - G reactants ( A Rx proceed only if ΔG<0 ) ΔG: the reaction is at equilibrium The reaction always moves from a situation of high potential energy to one of lower potential energy. A pathway must satisfy minimally two criteria: (1) The individual reactions must be specific . ( A reaction that is specific will yield only one particular product or set of products from its reactants) (2) The entire set of reactions that constitute the pathway must be thermodynamically
