What Effect Would Consumption of Cytochrome C Oxidase Inhibitor Have

Question

What effect would consumption of cytochrome c oxidase inhibitor have on an animal? A) The Krebs cycle would accelerate B) The electron transport chain would be halted C) NADH recycling to NAD⁺ would accelerate D) FADH2recycling will be directly inhibited

Accepted Answer

The electron transport chain would be halted. Cytochrome c oxidase is the final enzyme in the electron transport chain, and its inhibition would prevent the transfer of electrons to oxygen, which is the final electron acceptor. This would lead to a buildup of electrons in the electron transport chain, which would eventually halt the flow of electrons and the production of ATP.
