When the organism is resting and energy is not immediately needed, the reverse reaction takes place and the phosphate group is reattached to the molecule using energy obtained from food or sunlight.

ATP consists of an adenosine base (blue), a ribose sugar (pink) and a phosphate chain. The high-energy phosphate bond in this phosphate chain is the key to ATP's energy storage potential. Cells ...

When the organism is resting and energy is not immediately needed, the reverse reaction takes place and the phosphate group is reattached to the molecule using energy obtained from food or sunlight.

One amazing example is the way energy is stored and transported in every cell of every organism. The dominant strategy involves a molecule called ATP, which is synthesized from ADP and phosphate ...

ATP (adenosine triphosphate) is the energy-carrying molecule used in cells because it can release energy very quickly. Energy is released from ATP when the end phosphate is removed. Once ATP has ...
