Cards Term Energy Definition The ability to do work Term Energy: Types Definition *Kinetic - movement, ball in air, skiing, riding bikes, air molecule in room, electrons moving *Potential - not moving, stored energy, chair on ramp Term Energy: What forms may energy take? (3) Definition *Electrical - kinetic *Mechanical - kinetic *Chemical Term Metabolism Catabolic vs. Anabolic Definition All the reactions in the body that involve energy transformation *Catabolic - releasing energy, low entropy to high, big to small *Anabolic - need energy, high entropy to low, build bigger molecules ~one must predominate Term Energy Transfer Definition involves oxidation-reduction reactions -breakdown of substrate for energy involves transfer of electrons *intermediate carriers (NAD, FAD, ect) *to a final electron acceptor (oxygen) Term Aerobic Respiration Definition -convert sugar or fat to CO2 and H2O *transfer some of the energy released to make ATP -controlled release of energy in small steps *oxygen used only in the last step
