Metabolism review checklist Chapter 8: pages 142-159 (7 th edition: pages 141-157) Metabolism Metabolic pathways Catabolic pathway Anabolic pathway Energy: kinetic energy, heat, potential energy, chemical energy First law of thermodynamics Second law of thermodynamics Entropy Free energy (G), Free energy change ( G) G = DH - TDS G = G(final) – G(initial) Exergonic reaction Endergonic reaction ATP: structure and hydrolysis Energy coupling ATP hydrolysis coupled to cellular work (mechanical, transport, chemical): phosphorylation ATP cycle Enzyme Catalyst Activation energy (E A ) Substrate Active site Induced fit Substrate specificity How enzymes lower activation energy Enzyme activity and temperature/pH Functional partners of enzymes: cofactors/coenzymes/prosthetic groups (don’t worry about knowing differences between these) Enzyme inhibitors: reversible, irreversible, competitive, noncompetitive Metabolic regulation of enzyme activity Allosteric regulation of enzymes: activators, inhibitors
