You are interested in building a fully functional, bionic mitochondrion. In order to replicate the function of the F0 subunit of the ATP synthase in the normal mitochondrion, the F0 subunit in your bionic ATP synthase:. a. should undergo a mechanical rotation induced by passage of protons from the matrix to the intermembrane space that would result in ATP synthesis.
b. should include a series of smaller subunits within the F0 subunit that can bind ADP.
c. should have a structural connection or "bridge" that couples movements of the multiple subunits in the bionic F0 to conformational changes in F1.
d. should undergo a conformational change like that induced by uncoupling proteins in thermogenic brown fat that block proton gradients between the matrix and the intermembrane space.
e. should have enough rotating subunits to account for transfer of three ATP molecules from F1 directly into the intermembrane space in the bionic mitochondrion.
