Weightlifters, bodybuilders, and other athletes who require rapid bursts of high -energy muscle output often spend a lot of money on dietary supplements. Some supplements, such as amino acids, are used as building blocks to make more high-protein muscle cells. Other supplements increase energy or provide more endurance during workouts. For example, supplements that contain creatine (often sold as creatine diphosphate) are reputed to provide more energy. Based on this information and your knowledge of muscle physiology, would you expect creatine supplements to provide extra energy? Why or why not?
