Question

The primary medium for free energy storage in living cells isadenosine triphosphate (ATP). Its formation from adenosinediphosphate (ADP) is not spontaneous:

ADP^3- (aq) + HPO_4^2- (aq) + H+(aq) ---> ATP^4- (aq) + H₂O(l) ΔG = +34.5kJ

Cells couple ATP production with the metabolism of glucose (asugar):

C₆H₁₂O₆ (aq) + 6O₂(g) ----> 6CO₂ (g) + 6H₂O(l) ΔG = -2872kJ

The reaction of 1 molecule of glucose leads to the formation of38 molecules of ATP from ADP. Show how the coupling makes thisreaction spontaneous. What fraction of the free energy released inthe oxidation of glucose is stored in the ATP?
