Overview of Respiration using chemical energy - only autotrophs can use energy of sunlight through photosynthesis heterotrophs - use autotrophs for food; accounts for 95% of earth's organisms digestion - 1st step of harvesting energy; breaks down large molecules into smaller ones catabolism - harvesting energy from C-H and other chemical bonds cellular respiration - harvests energy by shifting electrons from 1 molecule to the next energy from electrons used for ATP, or lost as heat electrons at end of process lose most of their energy, get transferred to final electron acceptor aerobic respiration - where final acceptor is oxygen anaerobic respiration - where final acceptor is nonorganic molecule other than oxygen fermentation - where final acceptor is organic molecule C6H12O6 + 6O2 >> 6CO2 + 6H2O -720 kilocalorie change per mole in free energy ATP synthase - enzyme that creates most of ATP uses energy in gradient of protons produced by pumping protons across the membrane
