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

The Relative Efficiency of ATP Synthesis in Noncyclic versus Cyclic Photophosphorylation If noncyclic photosynthetic electron transport leads to the translocation of 7 H+/2e- and cyclic photosynthetic electron transport leads to the translocation of 2 H+/e-, what is the relative photosynthetic efficiency of ATP synthesis (expressed as the number of photons absorbed per ATP synthesized) for noncyclic versus cyclic photophosphorylation? (Assume that the CF1CF0-ATP synthase yields 3 ATP/14 H+.)
Given what you know about the involvement of nicotinamide nucleotides inoxidative and reductive metabolic reactions, predict whether the followingintracellular concentration ratios should be 1, > 1, or < 1. Explain youranswers.(a) [NAD+] >[NADH](b) [NADP+] >[NADPH](c) Since NAD+ and NADP+ are essentially equivalent in their tendency to attract electrons, discuss how the two concentration ratios might bemaintained inside cells at greatly differing values.

ATP Synthase is known to catalyze the synthesis of ATP with a ΔG°’ close to zero, and a Keq' close to. Why is the value of ΔG°’ different from the known value which is 30.5 kJ/mol (the energy for the reverse of ATP hydrolysis)? If the Keq' value is close to one, how is it ensured that the reaction is driven to the product side and more ATP is obtained?
Suppose you're given the following information: ATP + H2O → ADP + Pi ΔG'° = -30.5 kJ/mol Phosphoenolpyruvate + H2O → Pyruvate + Pi ΔG'° = -61.9 kJ/mol What would the ΔG'° be for the reaction phosphoenolpyruvate + ADP → pyruvate + ATP? Please answer in units of kJ/mol, but do not include the units in your answer.
