Select the statement below that best describes the key structure/function relationship of the ATP synthase complex.
a. Proton flow through the F. subunit causes rotation of the entire F1 subunit. including the catalytic headpiece which alters the affinity of the beta subunits for ATP and releasing the newly synthesized ATP.
b. The ATP synthase can only run in one direction in vitro, namely in the direction to synthesize ATP.
c. The gamma subunit is asymmetric, therefore as it rotates in 120° steps in response to proton flow through Fo, it makes 3 different contacts resulting in 3 different conformations of the beta subunits.
d. ATP synthase consists of three mechanical parts, all of which rotate using kinetic energy from redox. In hrane reveal its composition to be What is true of these proteins.
