Explain how energy is released from an ATP molecule

Hi,
ATP is highly soluble in water and is quite stable in solutions between pH 6.8?7.4, but is rapidly hydrolysed at extreme pH. Consequently, ATP is best stored as an anhydrous salt.
ATP is an unstable molecule and tends to be hydrolysed in water.
Any system that is far from equilibrium contains potential energy, and is capable of doing work.
Biological cells maintain the ratio of ATP to ADP at a point ten orders of magnitude from equilibrium, with ATP concentrations a thousandfold higher than the concentration of ADP. This displacement from equilibrium means that the hydrolysis of ATP in the cell releases a great amount of energy
The net change in heat energy (enthalpy) at standard temperature and pressure of the decomposition of ATP into hydrated ADP and hydrated inorganic phosphate is ?20.5 kJ/mol, with a change in free energy of 3.4 kJ/mol
Under typical cellular conditions, that is approximately ?57 kJ/mol (?14 kcal/mol).

hope that suffices. Isisla29 ...

ATP stands for Adenosine Triphosphate. This means that its structure has 3 phosphate molecules bonded on to the end of it. the third bond is a high energy bond, meaning that it takes a lot of energy to add on the phosphate and yields quite a bit when the bond is broken. So ATP basically acts as short term energy transfer and storage.

ATP stands for Adenosine Triphosphate, it is a coenzyme consisting of a sugar group, adenine a nucleobase and three phosphate groups.

One of the bond between the phosphate group is broken to release about 30.5 kJ/mol.

This hydrolysis produces ADP and which can be further hydrolyzed to AMP.

ATP is Adenosine triphosphate. It is a molecule in which energy is stored in the body in the form of chemical energy. An ATP molecule contains three phosphate ions. The chemical bonds with which these are attached in the molecule are covalent bonds and these bonds contain the energy required for the body.

OK I agree with all the answers above but I read this post to find out how this ATP energy does work. We do not have internal steam engines that run on heat. We have muscles of actin and myosin that use ATP to make movement that does work. How, I do not know. Anyone?

ATP stands for Adenosine Triphosphate it is a molecule made up made up of adenosine and 3 phosphates. when a phosphate is removed from ATP, a high energy chemical bond is broken and energy is released.
ATP=ADP (diphosphate) +p+ energy

Energy is released from the ATP molecule through the breakdown of chemical bonds.
