Ubiquinone
ubiquinone carries electrons from NADH dehydrogenase to cytochrome C reductase.
The NADH dehydrogenase complex is the largest respiratory enzyme complexes. It transfers eletrons through a flavin to ubiquinone, which passes the lectrons to cytochrome C reductase.

What is the function of cytochrome c in the electron
transport chain?
Question 3 of 4 To answer this question, you may reference the Metabolic Map. What is the function of cytochrome c in the electron transport chain? o It reduces two molecules of Q to QH2. It oxidizes NADH to NAD+. It oxidizes FADH2 to FAD. It transports two electrons from NADH or FADH to complex III. It transports an electron from complex III to complex IV.
