In the cell its energy source comes from the chemical compound ATP. ATP helps the cell carry on 3 main types of work. Mechanical (cell movement), chemical (anabolism), and transport (pumping materials into and out of the cell). ATP ( adenosine triphosphate) is constructed of a molecule of adenine attached to a molecule of ribose sugar which is attached to 3 phosphates. The energy is stored in the phosphate bonds.

ATP + H2O ---------------> ADP + P + G = -7.3 kcal / mol
This occurs in a test tube. In the human cell -10 / -12 kcal / mol are given off.

ATP transfers this energy to what ever it is reacting with.

ATP is renewable. ADP + P ------------------> ATP G = + 7.3 kcal / mol (endergonic)

Structurally, ATP consists of the adenine nucleotide (ribose sugar, adenine base, and phosphate groups. The nergy transfers from chemical bonds to endergonic (energy absorbing) reactions within the cell.

here is a simple answer!

ATP has three phosphate groups attached to it.

The energy is stored in these three phosphate groups. Every time ATP reacts, it loses a phosphate group, and the energy is released from the reaction. You also get ADP(DiPhosphate) and AMP(MonoPhosphate). ATP is The high energy version.

I think ATP( adenosine triphosphate ) is basic and primary form of energy needed by our body cells in aerobic respiration and mitochondria is the organelles where the ATP created and from there the ATP is carried to all parts of the body as energy source. :-!
