adenosine triphosphate. it is produced during aerobic respiration in the mitochodria of cells (38 ATP to be exact for every molecule of glucose) and is used to provide energy for the body.
it is termed the molecular currency for intercellular transfer. ATP is regenerated from ADP (adenosine diphosphate) and the amount of ADP and ATP in the body is always usually the same.

Adenosine Triphosphate can carry chemical energy for the cell. It's visualized easily like this:

A-P-P-P

Above, we have an adenosine group represented by "A", and phosphate groups by "P". The dashes are bonds between the groups.

When the cell needs energy, it will use the energy released when the last "P" (phosphate group) breaks off from ATP. So, the molecules will look like this:

A-P-P P

And the molecule represented by "A-P-P" is ADP, or adenosine diphosphate. So, because a bond was broken, the energy used by the molecule to hold the two parts together is now transferred to wherever the cell needs the energy to be used.

(Sometimes, TWO phosphates break off to create AMP, adenosine monophosphate, to yield "A-P" and "P-P", but that's not usually necessary to know in introductory biology.)

Adenosine 5'-triphosphate (ATP) is a multifunctional nucleotide primarily known in biochemistry as the "molecular currency" of intracellular energy transfer. In this role ATP transports chemical energy within cells. It is produced as an energy source during the processes of photosynthesis and cellular respiration. The structure of this molecule consists of a purine base (adenine) attached to the 1' carbon atom of a pentose (ribose). Three phosphate groups are attached at the 5' carbon atom of the pentose. ATP is also one of four monomers (nucleotides) required for the synthesis of ribonucleic acids. Furthermore, in signal transduction pathways, ATP is used to provide the phosphate for protein kinase reactions.
ATP energy is released when hydrolysis of the phosphate-phosphate bonds is carried out. This energy can be used by a variety of enzymes, motor proteins, and transport proteins to carry out the work of the cell. Also, the hydrolysis yields free inorganic Pi and ADP, which can be broken down further to another Pi and AMP. ATP can also be broken down to AMP directly, with the formation of PPi. This last reaction has the advantage of being an effectively irreversible process in aqueous solution.

A few examples of the use of ATP include the active transport of molecules across cell membranes, the synthesis of macromolecules (Eg. proteins), muscle contractions, endocytosis, and exocytosis.

Adenosine TriPhosphate.

It's the fuel for cellular processes. When it's used, it is reduced to Adenosine Diphosphate, as one of the phosphates is used to power whatever process the cell needs it for.
