The free energy change for the complete oxidation of one mole of glucose is -686 kcal and Δ G°' for the hydrolysis of ATP is -7.3 kcal\mol. How many moles of ATP could be synthesized if the entire oxidation process were 100% efficient in converting this energy to the production of ATP?

Quizplus · Accepted Answer

To find the number of moles of ATP that could be synthesized, divide the total energy released by the energy required to synthesize one mole of ATP: -686 kcal / -7.3 kcal/mol = 94.0 mol ATP. This assumes 100% efficiency in energy conversion.
