Photosynthetic Phosphorylation and Oxidative Phosphorylation Appear to Be Generally Similar

Photosynthetic phosphorylation and oxidative phosphorylation appear to be generally similar processes, both consisting of ATP synthesis coupled to the transfer of electrons along an electron carrier chain. Which statement is NOT true of both processes?

A) Both contain cytochromes and flavins in their electron carrier chains.
B) Both processes are associated with membranous elements of the cell.
C) Both use oxygen as a terminal electron acceptor.
D) Each represents the major route of ATP synthesis in those cells in which it is found.
E) Protons are pumped from the inside to the outside of both mitochondria and chloroplast membranes
