Can anything that release phosphate produce energy equivalent to ATP?

[scilearner]

If a diphosphate is broken down by water into 2 phosphates is the energy released equivalent to an ATP. Does ATP provide more energy?

[Mr Skeptic]

ATP (Adenosine Tri-Phosphate) is usually broken down to ADP (Adenosine Di-Phosphate), releasing energy. Breaking down ADP would also release energy, but I think it is harder to add the phosphates back to it. Remember, ADP gets recycled to produce ATP again by adding energy to it. The efficiency of the addition and removal is quite significant, much more so than how much energy can be extracted from each molecule.

 

GTP (Guanosine Tri-Phosphate) works much like ATP, same with CTP and UTP. The difference between these is the "letter" from RNA that it uses as the base of the molecule, and also most processes use ATP.

You need to check out the corresponding thermodynamic data, chemcial potential difference in the process you mentioned might be similar but there might be differnece in terms of entropy.
