(Glutamic acid + NH₃)is converted to glutamine ΔGᵒ' = +14.2 kJ/mole.Coupling this reaction with ATP hydrolysis yields an overall free energy value of:

Question

Quizplus · Accepted Answer

The conversion of glutamic acid to glutamine requires energy, indicated by a positive ΔGᵒ' value of +14.2 kJ/mole. ATP hydrolysis releases energy, typically around -30.5 kJ/mole. When these two reactions are coupled, the overall free energy change is the sum of the two individual changes: +14.2 kJ/mole (for the conversion) - 30.5 kJ/mole (for ATP hydrolysis) = -16.3 kJ/mole, indicating that the coupled reaction is energetically favorable.
