Question 1: The excitation, contraction, and relaxation of skeletal muscle require the use of ATP. Because only limited stores of ATP are immediately available in muscle tissue, ATP must be continually supplied if contractile activity is to continue. Depending on the type of movement or exercise, one or more pathways can be used to provide the most efficient way of supplying the ATP. For example, a cross-country skier who skis continuously for two hours during a training exercise will need a sustained source of ATP. Which one? Oxidative phosphorylation Glycolysis Using creatine phosphate Question 2: To prepare for the cross-country meet, a skier decides to significantly increase the amount of carbohydrates in his diet (a technique also known as carbohydrate loading). Why might this be beneficial to the cross-country skier? Check all that apply. Carbohydrates are used to build actin filaments in the myofibrils, which increases muscle bulk and performance. Eating more carbohydrates leads to more glycogen stores in muscles, which then equates to larger energy stores for short, explosive bouts of energy use. The liver can store copious amounts of ingested carbohydrates as glycogen, which can then be slowly broken down to release the glucose needed to fuel aerobic respiration. As long as oxygen is present, the glucose stored in the ingested carbohydrates can provide a steady stream of ATP, thus meeting the demands of prolonged periods of exercise.

Long-term exercise requires aerobic respiration, which makes the maximum amount of ATP possible. Aerobic respiration will be supported as long as cardiopulmonary function continues. For immediate energy, the myoglobin in muscle fibers can supply oxygen for limited cellular respiration. For short-term energy needs, glucose can be released from storages of glycogen chains. During exercise, different mechanisms of ATP production are used based on the duration of exercise.

Discuss the oxidative phosphorylation energy system in terms of speed of action, amount of ATP replenished, and duration of action. Explain why this system is aerobic and the differences between utilizing glucose and glycogen. Dietary protein must be consumed daily because nitrogen is lost in ________ and ________.
