ATP synthase, shown below, uses the proton (H ) gradient to drive ATP synthesis. Put the following steps of ATP synthesis in order from proton transport to the synthesis of ATP:
a. The y subunit rotates and interacts with the three alpha beta subunit pairs, causing confrontational changes in the beta subunit
b. protons from the intermembrane space bind to proton binding sites on c subunits
c. each beta subunit ADP and Pi, converts ADP + Pi to ATP, and releases ATP once during one turn of the y subunit
d. as the c ring rotates past the a subunit, c subunits release their protons into the matrix
e. the y subunit rotates along with the c subunit
