E. All of the above are true
Which of the following statements concerning ATP synthesis is NOT true?
a.
The open conformation of the ATP synthase is for releasing ATP.
b.
The gamma subunit in the stalk responds to the flow of H+ and rotates the assembly counterclockwise and thus change the conformations of the active site to synthesize ATP.
c.
The tight conformation of the ATP synthase is for converting ADP and phosphate to ATP.
d.
The loose conformation of the ATP synthase is for binding ADP and phosphate.
e.
Ten protons are required to catalyze the rotation of the subunits so that one ATP is synthesized.
