Cyanide and carbon monoxide block the final step in the electron transport chain. Consequently, ATP production in the mitochondria would

A. not change, because protons cross the outer mitochondrial membrane to produce ATP.
B. increase, because this would spontaneously establish a stronger proton gradient.
C. decrease, because electrons would not move through the electron transport chain and reduce oxygen.
D. decrease, because protons would not be able to move across the inner mitochondrial membrane.
E. increase, because this would make more oxygen available in the mitochondrial matrix.
