Equation for the hydrolysis of ATP is written as follows: ATP + H2O → ADP + Pi + free energy
Equation for the hydrolysis of ADP is written as follows: ADP + H2O → AMP + Pi + free energy
Hydrolysis means splitting of molecule in presence of water. It is catabolic reaction.
ATP + 2H₂O → ADP + Pi [H₃O]⁺+ energy
[H₃O]⁺ is hydronium ion
ADP + 2H₂O → AMP + Pi [H₃O]⁺+ energy
[H₃O]⁺ is hydronium ion and AMP is adenosine mono phosphate
