Explanation / Answer

Hi Answer:

Interpret the effect of cyanide or Carbon monoxide on the electron Transport Chain.

Q. Cyanide and carbon monoxide block the final step in the Electron Transport Chain, What effect would this have on ATP production in the mitochondria? :

Answer: Option C [ATP production would decrease, because electron would not move through the electron transport chain and reduce oxygen.]

Explanation: Cyanide and Carbon monoxide blocks the electron flow by binding at the cytochrome c. Cyanide reacts with the ferric form of heme a 3 and carbon monoxide inhibit the ferrous form. This inhibits or blocks the electron transport chain which also inhibits the ATP synthesis because the proton motive force is not generated due to blockage of electron transport chain.
