Question

Movement of protons down the electrochemical gradient through the F₀F₁ ATP synthase a subunit rotates:

The a subunit and rigidly attached b subunits

The c subunit ring and rigidly attached γ subunit

The F₁α and β subunits

The c subunit ring, γ subunit, and the α and β subunits

None of the above

Correct.

Incorrect.

Question

Which of the following is not directly part of the F₀F₁ ATP synthase binding change mechanism for F₁β subunit formation of the phosphoanhydride bond between ADP and P_i?

All are part of the binding change mechanism

Protons move down an electrochemical gradient through a proton channel at the interface between the a subunit and c subunit ring

Each β subunit has three distinct structural and functional states – O, L, and T.

Formation of the phosphoanhydride bond is catalyzed in the β subunit T state and the ATP is released in the O state.

The rotational position of the γ subunit determines the structural and functional state of each β subunit.

Correct.
