question 20

Multiple Choice

How does the proton motive force lead to production of ATP?

• C) Oxidative phosphorylation of ADP by ATP synthase requires protons as cofactors in the reaction.
• D) Translocation of three to four protons drives the F₀ component of ATPase which in turn phosphorylates one ADP into ATP.
