HSC 120 Lecture Notes - Lecture 10: Phosphocreatine, Excess Post-Exercise Oxygen Consumption, Glycolysis
Document Summary
Muscle metabolism: can do aerobic or anaerobic respiration to process energy. Aerobic respiration: many-step process that produces enough energy to generate 36 atp molecules for every glucose molecule but requires the addition of oxygen. Aerobic: total of 36 atps per glucose molecule. Creatine phosphate: storage form of readily available energy. Formed by aerobic respiration when muscle is resting. Energy is transferred back to adp when atp levels decrease. Fatigue: inability of a muscle to respond to a nerve stimulus. The amount of oxygen needed to remove the lactic acid is called oxygen debt. Can result from the buildup of lactic acid, the lack of acetylcholine, or the lack of glucose. Slow twitch fibers: specialized for aerobic respiration, so they do not fatigue quickly.
