Question 1

How does the rotation of the c ring lead to ATP synthesis?

Accepted Answer

A)  The c ring is linked tightly to the gamma and epsilon subunits in the stalk of F1. 
B)  The c ring interacts with the beta subunit. 
C)  The gamma subunit rotates with proton gradient formation, inducing the binding-change mechanism. 
D)  All of the above. 
E)  None of the above.
