The formation of ATP by ATP Synthase is part of a coupled reaction, asdiscussed in class. Given the information below and using what you knowabout ATP Synthase and the proton motive force, calculate the overall AGand determine if the coupled reaction is favorable overall. Note that youdo not need to worry about intermediates like we did for the classexample.ADP + Pi → ATP has a AG = 7.3 kcal/mol2 moles of protons traveling back down their gradient across the innermitochondrial membrane has a AG = -10.28 kcal/mol%3DO a. Overall AG = -17.58 kcal/mol, favorable overallO b. Overall AG = -2.98 kcal/mol, favorable overall%3DO c. Overall AG = 2.98 kcal/mol, unfavorable overallO d. Overall AG = 17.58 kcal/mol, favorable overall
