In your body its THE energy source (ATP -> ADP).
ATP (adenosine triphosphate) is a high-energy molecule that serves as a temporary energy storage in cells and fuels cellular processes. ADP (adenosine diphosphate) is the product formed when ATP is broken down to release energy. While ATP is a fuel for cellular activities, ADP is the result of ATP breakdown and needs to be converted back to ATP to be used as a source of energy.
ADP has less potential energy than ATP has. In fact, there are 7.3 kc less energy in ADP than in ATP.

ATP (adenosine triphosphate) contains the most energy among AMP (adenosine monophosphate), ADP (adenosine diphosphate), ATP, and Pi (inorganic phosphate). This is because ATP has three phosphate groups that are high-energy bonds, making it a primary source of cellular energy. When ATP is hydrolyzed to ADP and Pi, energy is released, which can be used by cells for various processes.
The immediate source of energy to reform ATP into ADP molecules is the breaking of high-energy phosphate bonds within the cell. This process releases energy that can be used to drive the conversion of ADP back into ATP through the process of phosphorylation. Phosphorylation involves the addition of a phosphate group to ADP, which requires energy input to form the high-energy phosphate bonds in ATP.
adp+p(i)--->atp ADP +P ---> ATP
Usually energy in the body's obtained from converting ATP into ADP. However, glycolysis, the process of converting glucose to pyruvate, releases energy that turns ADP into ATP.
ATP has higher potential chemical energy compared to ADP due to the presence of an extra phosphate group in ATP. This extra phosphate group allows ATP to store and release energy more readily during cellular processes. When ATP is hydrolyzed to ADP, energy is released and can be used by the cell for various functions.
The equation for reforming ATP from ADP and inorganic phosphate is: ADP + Pi + energy → ATP. This process is catalyzed by the enzyme ATP synthase during cellular respiration.
Adenosine triphosphate (ATP) is a multifunctional nucleotide that is most important as a "molecular currency"of intracellular energy transfer. Adenosine diphosphate (ADP), a nucleotide, is an important part of photosynthesis and glycolysis. ADP can be converted into ATP and is also the low energy molecule. ATP is the breakdown of food molecules. ATP is high energy bond as compared to ADP. ATP has three phosphate bonds and ADP has two phosphate bonds. Rest of the structure is common to both.
ATP or adenosine triphosphate. When ADP, adenosine diphosphate, gets a third phosphate group, it becomes ATP. ATP is the energy source of many reactions in the cell. When a reaction needs energy to occur, the enzyme that catalyzes the reaction also cleaves a molecule of ATP into ADP and phosphate. The energy of the phosphate bond is used to fuel the endothermic reaction. The ATP is regenerated (phosphorylation of ADP) in the glycolysis or another process that generates energy.
