ATP synthase is composed of two major complexes: $F_0$ which is in the membrane and $F_1$ which is outside of the membrane. The complexes are connected to each other via the axle and stator. Both the $F_0$ and $F_1$ complexes have different functions. One complex turns while the other remains stationary and each complex interacts (binds) with different molecules.
Which of the following MOST accurately describes the movement and function of the $F_0$ and $F_1$ subunits when the ATP synthase is converting ADP and Pi into ATP?
