Fig. 1: ATP Cycle
To trap energy released from catabolic
chemical reactions, the cell uses that released energy to attach a phosphate
group onto ADP (adenosine diphosphate) to make ATP (adenosine triphosphate).
Thus, energy is trapped and stored in high-energy phosphate bonds. To obtain
energy to do cellular work, the cell enzymatically removes the third phosphate
from ATP thus releasing the stored energy and forming ADP and phosphate once
again.
