As it says above, I really want to know!
An answer is on Wikipedia at: http://en.wikipedia.org/wiki/Adenosine_triphosphate under ‘Physical and chemical properties’.
Estimates vary - see also: http://hypertextbook.com/facts/2000/AmberIqbal.shtml Under normal biological conditions ATP hydrolysis to ADP releases somewhere in the region of 25-50 kJ per mole of which about 40-60% produces heat and the rest is used for other biological processes.
According to http://www.worldofmolecules.com/life/atp.htm “The total quantity of ATP in the human body is about 0.1 mole. The energy used daily by an adult calls for the hydrolysis of 200 to 300 moles of ATP. This means that each ATP molecule has to be recycled 2000 to 3000 times during the day. ATP cannot be stored and so its synthesis has to closely follow its consumption.”
An alkaline long-life AAA battery stores about 5,000 J of energy!
