The free energy change for the complete oxidation of one mole of glucose is -686 kcal and $\Delta$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?

Question

Quizplus · Accepted Answer

The free energy change for the complete oxidation of one mole of glucose is -686 kcal. The efficiency of converting this energy into ATP is 100%, so the total free energy change available for the synthesis of ATP is -686 kcal/mol.

The energy released by the hydrolysis of one mole of ATP is -7.3 kcal/mol.

Therefore, the number of moles of ATP that could be synthesized from the complete oxidation of one mole of glucose is:

686 kcal/mol / 7.3 kcal/mol = 94.0 mol ATP.

Thus, the answer is B.
