D
ATP synthase becomes active only when there is a proton gradient having a higher concentration of protons (H+) on the inner side (F1 side) as compared to the outer side (F0 side).

Solution
The correct option is D ATP synthase becomes active only when there is a proton gradient having a higher concentration of protons (H+) on the inner side (F1 side) as compared to the outer side (F0 side).
ATP synthase is located in F1 or headpiece of F0−F1 or elementary particles. The particles are present in the inner mitochondrial membrane. ATP-synthase becomes active in ATP formation only when there is a proton gradient having a higher concentration of H+ or protons on the F0 side as compared to F1 side. Increased proton concentration is produced in the outer chamber or outer surface of the inner mitochondrial membrane by the pushing of protons with the help of energy liberated by the passage of electrons from one carrier to another.
