9.69 in Sixth Edition

Postby Alexa Tabakian 1A » Tue Feb 19, 2019 9:46 am

What amount (in moles) of ATP could be formed if all the Gibbs free energy released in the oxidation of 3.00 mol NADH were used to generate ATP?

I do not know how to approach this problem given just three equations and delta G. Can anyone help me out?

Since reactions 2 and 3 are the ones used to drive the regeneration of ATP, I would first use them with the Hess's Law-like method to figure out the ∆G of the reaction, taking into account 3 moles of NADH. Then to get it with respect to ATP, divide by the ∆G you calculated divded by the ∆G for the reaction with ATP do get the amount of moles regenerated if all of the free energy released was used to drive the reaction.
