Free energy of atp hydrolysis

WebThe free energy of ATP hydrolysis was calculated from the equilibrium of the creatinekinase reaction, taking into account the pH-dependence of the equilibrium constant, and intracellular inorganic phosphate. In control aerobic hearts the mean free energy of ATP hydrolysis was 55.2 kJ/mol. Both during ischemia and anoxia it declines biphasically. http://book.bionumbers.org/how-much-energy-is-released-in-atp-hydrolysis/#:~:text=Under%20%E2%80%9Cstandard%E2%80%9D%20conditions%20%28i.e.%20concentrations%20of%201M%20for,on%20the%20concentration%20of%20the%20cation%20Mg%202%2B.
