試題詳解

61. Which option listed in below is INCORRECT that describe about "ATP synthesis"?
(A) H+ ions flowing down their gradient enter a half channel in a stator, which is anchored in the membrane.
(B) H+ ions enter binding site within a rotor, changing the shape of each subunit so that rotor spins within the membrane.
(C) Each H+ ion makes one complete turn before leaving the rotor and passing through a second half channel in the stator into the mitochondrial matrix.
(D) Spinning of the rotor causes an internal rod to spin as well. This rod extends like a stalk into the knob below it, which is held stationary by part of the stator.
(E) Turning of the rod activates catalytic sites in the knob that produce ATP from AMP and Pi.
