Does this figure have any inaccuracies? Yes, the arrows showing movement of protons from the matrix into the inner membrane are all pointing in the wrong direction and should be reversed. Yes, the position of ATP synthase relative to the inner membrane is incorrect and should be reversed so that ATP is shown being synthesized in the intermembrane space. Yes, the electrons are shown moving up as they pass along the respiratory chain but they should be shown moving down along the chain. Yes, the arrow showing movement of protons through ATP synthase is pointing in the wrong direction; it should be reversed. No, the figure is accurate as shown.
