The correct answer to this question is C, ATP, which stands for adenosine triphospate. It is the biochemical way to store and use energy. ATP comes from three biochemical systems found in the muscle. The first is phosphagen, which is made of ATP and creatine phosphate levels. Phosphagen supplies high rates of energy, which can last for 8-10 seconds.
The second is glycogen lactic acid. It makes ATP at a slower rate, but is fast enough to last for 90 seconds. The last system is aerobic respiration. This is the process where glucose is broken down into water and carbon dioxide. While it is the slowest of all three systems, ATP can last for hours in this system.
