Which of the Following Reactions is Possible by Reverse Electron

Question

Which of the following reactions is possible by reverse electron flow? A) reduction of Fe³⁺ to Fe²⁺ B) NADP⁺ reduction to NADPH C) protein biosynthesis D) reduction of oxygen by Fe²⁺ to form H2O and Fe³⁺ E) anammox

Accepted Answer

Reverse electron flow is a process used by some microorganisms to generate reducing power (NADPH) for biosynthetic reactions, such as the reduction of NADP⁺ to NADPH, by using energy from a proton motive force.
