Phosphorus in Energy Production
Another vital role of phosphorus is in energy production and the storage of energy in the body. The energy currency of the body, when fully charged, is known as adenosine triphosphate (ATP). Adenosine can be attached to one, two, or three phosphate groups, as shown in Figure 10-3. ATP refers to adenosine with three phosphate groups attached. When used for energy, ATP discharges to adenosine diphosphate (ADP), which has only two phosphate groups attached.
ADP is able to be recharged into ATP in the cell by a process that turns the chemical bonds of energy-rich molecules such as glucose into energy. The more phosphate groups attached to adenosine, the higher the energy. AMP (adenosine monophosphate) has the least stored energy with only one phosphate group attached.
Phosphorus is also needed to form creatine phosphate. Creatine phosphate is an important energy store in skeletal muscles and the brain. It is made in the liver and is transported to the muscles and the brain. Creatine phosphate can

pump ADP up to ATP by donating a phosphate group, as seen in Figure 10-4. This happens in just two to seven seconds after an intense effort. After donating a phosphate group, creatine phosphate becomes creatine. This creatine can be recharged back into creatine phosphate.
