Question
The AG" of the dephosphorylation of phosphocreatine is -43.0 kJ/mol.
Phosphocreatine → creatine +Pi; -43.0kJ/mol
When coupled to the phosphorylation of ADP to ATP (+30.5kJ/mol)
ADP +Pi → ATP; +30.5 kJ/mol
calculate the actual, physiological AG for the following reaction in kJ/mol:
Phosphocreatine + ADP creatine + ATP
at 37°C, with concentrations as follows:
Phosphocreatine = 0.715 mM
creatine = 0.566 mM
ADP = 0.431 mM
ATP = 2.382 mM
