Document Summary

Anaerobic: not requiring oxygen to produce atp, glycolytic/non-oxidative, high-intensity exercise, short duration, atp-pc and anaerobic glycolysis system. Aerobic: requiring oxygen to produce atp, oxidative, oxidative phosphorylation, low-moderate intensity exercise, longer duration. Atp-pc system: first and quickest energy system, always used at the very start of exercise, pc + adp atp + c. Creatine kinase is the rate limiting enzyme for the reaction: exercise example shotput, duration 0-3 s, fuel storage site cytosol, atp reformation rate very rapid. In the liver, the cori cycle converts lactate to glucose. Differences between glycolysis and oxidative phosphorylation: without oxygen, pyruvate is converted to lactate. 1. 25. 17: with oxygen, pyruvate is shuttled to the mitochondria and begins the citric acid cycle (tca or krebs cycle. Tca cycle: pyruvate from glycolysis is shuttled into the mitochondria to start the reaction, nadh & atp inhibit the reaction, adp, p, ca, nad activate the reaction.
