They basically provide an alternative path for the protons to re-enter. Therefore, since the protons don\'t go through FOF1 atp synthase ATP cannot be produced. The electron transport chain is not affected by DNP. The electrons continue to flow normally. So the correct answer is choice a Solution They basically provide an alternative path for the protons to re-enter.
