Chemical Reactions A chemical reaction occurs when reactants combine to generate one or more products • All chemical reactions in the body constitutes metabolism • Metabolism provides for the capture, storage and release of energy Basic energy concepts • Work = movement of an object or change in its physical structure • Energy = the capacity to perform work • Kinetic energy is energy of motion • Potential energy is stored energy resulting from position or structure • Conversions are not 100% efficient, resulting in release of heat Metabolism • Types of reaction • Decomposition • Synthesis • Exchange • Metabolism is the sum of all reactions • Through catabolism cells gain energy (break down of complex molecules) • Anabolism uses energy (synthesis of new molecules) Reversible reactions • All reactions are theoretically reversible
