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.
In the electron transport chain, Cytochrome Coxidase obtains electrons from Cytochrome C a. Ob. Ubiquinone Oc Cytochrome Creductase Od. NADH dehydrogenase
1.) Which of the following has a higher affinity for electrons? A.) NADH dehydrogenase complex B.) Cytochrome C Reductase complex
biochemistry help The standard free energy change for the transfer of electrons from NADH to one of the participants below is -70.4 kJ/mol. What is the identity of this acceptor?

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.
