Which of the following statements comparing the ATP synthase complex in cellular respiration and photosynthesis is not true? A)Both require the movement of H⁺ from inside a compartment to outside of the compartment. B)Both produce ATP. C)Both work via chemiosmosis. D)Both require a H⁺ gradient. E)Both are located in a membrane.

Quizplus · Accepted Answer

In photosynthesis, the movement of H+ ions (protons) from inside the thylakoid compartment to the outside of the compartment generates the gradient that drives ATP synthesis by ATP synthase. However, in cellular respiration, the movement of H+ ions (protons) from outside the mitochondrial matrix to the inside generates the gradient that drives ATP synthesis by ATP synthase. Therefore, only cellular respiration requires the movement of H⁺ from inside a compartment to outside of the compartment.
