(BIOCHEMISTRY QUESTION) Which of the following statements is correct?

a. the proton gradient produced by the electron transport chain is used by ATP synthase to form the phosphoanhydride bond in ATP

b. the proton gradient provides a driving force for rotation of the Fo subunit. This ratchet motion is utilized to induce a conformation change in the F1 component allowing non-covalent interaction with ATP to be broken releasing ATP into solution

c. ATP synthesis (ATP released into solution) does not require energy as long as you use ATP synthase, due to the fact that the enzyme makes the formation of the phosphoanhydride favorable

d. none of the above are correct and therefor D is my best choice

Explanation / Answer

The answer B is correct the proton gradient provides a driving force for rotation of F0 subunit. This ratchet motion is utilized to induce a conformation change in the F1 component allowing non-covalent interaction with ATP to be broken releasing ATP into solution.
