Which of the following is NOT a characteristic of proton gradient-driven enzyme conformational change in ATP synthase? A)binding of substrates B)catalytic cooperativity between subunits C)conformational change in the β-subunits releasing ATP D)rotation of (αβ)₃ complex relative to a fixed β-subunit

Question

Quizplus · Accepted Answer

The correct answer is D because ATP synthase operates through the rotation of the γ-subunit within the (αβ)_3 hexamer, not the rotation of an (αβ)₃ complex relative to a fixed β-subunit. This rotation is driven by the proton gradient across the membrane, leading to conformational changes in the β-subunits that facilitate ATP synthesis.
