What effect does Cyanide have on NAD+ and NADH production in Complex IV of the Electron Transport Chain? Why would cyanide cause High NADH concentrations and low NAD+ concentrations?
Homework Answers
cyanide will bind with the heam group of the cytochrome protein and stop the conversion of NADH to NAD+ (electron transfer). hence ATP will not be generated. because NADH, due to cytochrome protein inactivation, will not transfer electron further and hence accumulate in high quantity as compare to NAD+.

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.
