Final answer:
Glycolysis and the phosphagen system are used in both aerobic and anaerobic exercise to generate energy. Glycolysis breaks down glucose to produce ATP, while the phosphagen system rapidly regenerates ATP using creatine phosphate.
Step-by-step explanation:
In both aerobic and anaerobic exercise, the glycolysis and phosphagen systems play important roles in generating energy. Glycolysis is the breakdown of glucose into two molecules of pyruvate, while the phosphagen system involves the use of creatine phosphate to rapidly regenerate ATP. In aerobic exercise, glycolysis occurs in the presence of oxygen and produces ATP, while in anaerobic exercise, glycolysis occurs in the absence of oxygen and produces lactate.
