Cyanide and Carbon Monoxide Block the Final Step in the Electron

question 1

Multiple Choice

Cyanide and carbon monoxide block the final step in the electron transport chain.What effect would this have on ATP production in the mitochondria?

• A)Reduction, because protons would not be able to move across the inner mitochondrial membrane
• B)No effect, because protons cross the outer mitochondrial membrane to produce ATP
• C)Reduction, because electrons would not be able to move through the electron transport chain
• D)Increase, because this would spontaneously establish a proton gradient
• E)Increase, because this would make more oxygen available in the mitochondrial matrix
