How Does the Proton Motive Force Lead to Production of ATP

question 20

Multiple Choice

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

• A) ATPase requires one proton to make one ATP.
• B) Protons must be pumped against a concentration gradient from outside of the cell into the cell to rotate the F₀ subunit of ATPase for the F₁ subunit to make 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.
