Document Summary
Lecture 3 - track and field, rowing, soccer. Soccer: 10% anaerobic, 80% of the time is low intensity, hr avg is 170. Cofactor: a nonprotein component that enables the structure/ t between the enzyme and substrate to be a closer match. They have an identical function, the only di erence is that it is organic: without the coenzyme, the enzyme will not function. Atp - pcr system: involved with changes in energy demand/speed during aerobic exercise, atp use can occur very rapidly, cells contain a storage form of high energy known as phosphocreatine (pcr) or. Concentration of pcr is 4-5x greater than that of atp. Gives high power output from 3-15s in an all out e ort - rst 3 seconds is just. Atp, after that pcr comes and replenishes the atp: key concept is that recovery is something that happens aerobically.
