Question

does this figure have any inaccuracies?
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.
no, the figure is accurate as shown.
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 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.

Explanation:

In cellular respiration, protons flow from the inter - membrane space into the mitochondrial matrix through ATP synthase to generate ATP. In the figure, the direction of proton movement through ATP synthase is incorrect. Protons should move from the inter - membrane space (higher proton concentration) to the matrix (lower proton concentration), but the arrow in the figure points in the wrong direction.

Answer:

Yes, the arrow showing movement of protons through ATP synthase is pointing in the wrong direction; it should be reversed.
