Adenosine triphosphate (ATP) is considered to be the energy currency of life. It is the high-energy molecule that stores the energy we need to do just about everything we do. ATP can power needed reactions by losing one of its phosphorus groups to form ADP, but you can use food energy in the mitochondria to convert the ADP back to ATP so that the energy is again available to do needed work. Complete the activity to order the general steps of the ATP-ADP cycle in aerobic cellular respiration.
