Which of the Following Statements Correctly Describes What Happens During

Which of the following statements correctly describes what happens during chemiosmosis?

A) Protons are added directly to ADP to recharge it to ATP.
B) Protons flow through the ATP synthase enzyme from the side of the membrane where they are lower in concentration to the side where they are higher in concentration.
C) The purpose is to generate water from oxygen.
D) Only electrons from the reduced carrier NADH are deliver to the electron transport chain; the reduce carrier FADH₂ takes its electrons elsewhere.
E) The energy of protons flowing through the ATP synthase enzyme powers the recharge of ADP to ATP.
