The primary role of the F₀ part of the ATP synthase complex in chemiosmotic ATP synthesis is:
- ACatalyzing the synthesis of ATP from ADP and Pi.
- BActing as a channel for proton diffusion across the thylakoid membrane.
- CBinding ADP and Pi at its catalytic sites.
- DPumping protons from the stroma into the thylakoid lumen.
