In eukaryotes, NADH is the most important electron donor. The associated electron transport chain is NADH → Complex I → Q → Complex III → cytochrome c → Complex IV → O2 where Complexes I, III and IV are proton pumps, while Q and cytochrome c are mobile electron carriers. The electron acceptor for this process is molecular oxygen. In prokaryotes (bacteria and archaea) the situation is more complicated, because there are sever… WebFour distinct suggestions have been made to explain the mechanism of the cytochrome b (5)-imposed positive modifier action of the cytochrome P450 monooxygenase reaction. The first mechanism involves a direct input of an electron into the monooxygenase cycle.
