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.

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 ...

Figure 1: ATP concentration affects signal efficacy of CFP-YFP–based FRET sensors. It is important to note further that the ratio changes (8–45% change in YFP/CFP ratio) are within the range ...

This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon ... Adenine is also a component of important biomolecules such as ATP (adenosine ...
