Solution

The c subunits are responsible for the rotation in ATP synthase needed to produce ATP. This is because the c subunits form a ring in the membrane that rotates as protons move through the ATP synthase complex. This rotation is transferred to the catalytic part of the ATP synthase (the F1 part), which triggers conformational changes that allow ATP synthesis.
