Answer to Question 1

At the onset of exercise, small amounts of ATP already present in muscle tissue provide an immediate source of energy. This ATP reserve is quickly depleted, however. The phosphagen system is the simplest and most rapid means by which active muscles generate ATP. Under anaerobic conditions, the high-energy compound called creatine phosphate can be broken down. As a result, a molecule of phosphate is released, which combines with adenosine diphosphate (ADP) to produce ATP. Only small amounts of creatine phosphate are stored in muscle, and it takes several minutes to replenish that small supply. Therefore, if physical activity continues, muscles must turn to other systems to generate ATP.
