Forms of energy: Chemical energy – energy in the bonds of chemicals all reactions in cells Electrical energy – energy in the movement of charged particles Mechanical energy – energy used directly to move matter (muscle cells use mechanical energy) Radiant energy – energy that travels in waves (includes solar energy, light energy) Exergonic reactions: release energy Endergonic reactions: require (absorb) energy The rate of a chemical reaction is influenced by: 1. temperature : molecules move faster as the temperature is increased (increases collisions)… moderate temperature is best; high temperatures often denature (inactivate) enzymes 2. particle size : small molecules move faster (more (forceful) collisions) 3. concentration : usually increased reactant concentrations increases rate (more collisions) 4. catalysts : increase rate of chemical reactions without themselves being changed in the reaction…
