QUESTION 38 All of the following statements about mitochondrial oxidative phosphorylation are true EXCEPT O a. The proton-motive force is the potential energy created from the concentration gradient and charge difference of hydrogen ions. O b. The Fo unit of ATP synthase projects into the matrix O c. ATP synthesis occurs as the F₁ unit of ATP synthase rotates to expose active sites. O d. ATP synthase can also act as an ATPase, and the ATP synthesis function is favored. Oe.
