Study the following statements regarding chemiosmotic hypothesis in mitochondria.

(I) F1 head-piece contains the site for the synthesis of ATP from ADP + Pi.

(II) F0 part forms the channel through which protons cross the inner membrane.

(III) The passage of protons through the channel is coupled to the catalytic site of the F1 component for the ATP production.

(IV) For each ATP produced, 2H + pass through F0 from the intermembrane space to the matrix against the electrochemical process gradient.

Select the option depicting the correct statements.
