For the coupled reaction given below, the equilibrium constants (Keq) for equation [1] and equation [2] are 270 and 890, respectively.
Glucose 6-phosphate + H2O → glucose +Pi [1]
ATP + glucose → ADP + glucose 6-phosphate [2]
The standard free energy of hydrolysis of ATP at 25°C is
1
-(24 to 26) kJ/mol
2
-(18 to 20) kJ/mol
3
-(30 to 32) kJ/mol
4
-(60 to 62) kJ/mol
