Document Summary

Sun generates energy by fusing h atoms lecture 4: Vo2 max 45 ml/kg/min for heavy front row players to 65 ml/kg/min for 2nd row and back players. Fast jogging for 20 m- 90 x. 750 time per player per match (3-4 s) review: Key enzyme is myosin atpase- the more of this, the faster the muscle contraction. The more enzyme, a faster contraction and fast twitch muscle. Can replenish atp during exercise by breaking down pcr. The more reactions there are, the slower the rate of atp regeneration. Need this energy to form atp again. Consuming o2 at end of etc, using this energy produced aerobically to replenish atp and/or. Use atp to make energy and use pcr to generate atp. Cytosol/cytoplasm: where atp/ pcr and glycolysis is happening (anaerobic metabolism) Mitochondria: where aerobic metabolism is happening cell: Glucose in blood stream is tightly controlled. If this is a non exercise situation, the glucose will be stored as glycogen.
