Hi everyone here we have a question asking us in the electron transport chain cyanide binds to which of the following A cytochrome c reductase be cytochrome c oxidase, c n a d h q reductase or decide crumb seat. So if we look at complex four, we have cytochrome c oxides and two hydrogen plus one half +02 goes in and outcomes hydrogen ions. And on this side of chrome c oxidizes, there is a, he made a three prosthetic group and cyanide can bond to this. He may three prosthetic group and it will act as an inhibitor to the mitochondrial electron transport and that is why it is a poison. So our answer is B cytochrome c oxidase. Thank you for watching. Bye.
