Multiple Choice

What effect does cyanide have on the electron transport chain and the production of ATP in cellular respiration?

Cyanide has no effect on the electron transport chain or ATP production.

Cyanide inhibits cytochrome c oxidase, halting ATP production.

Cyanide acts as an electron donor, increasing ATP synthesis.

Cyanide increases the efficiency of ATP production by enhancing electron flow.

Verified step by step guidance

Understand the role of the electron transport chain (ETC) in cellular respiration: The ETC is a series of protein complexes located in the inner mitochondrial membrane that transfer electrons from electron donors to electron acceptors via redox reactions. This process creates a proton gradient that drives ATP synthesis through oxidative phosphorylation.

Identify the function of cytochrome c oxidase: Cytochrome c oxidase is the last enzyme in the electron transport chain, responsible for transferring electrons to oxygen, the final electron acceptor, and facilitating the formation of water.

Recognize the effect of cyanide on cytochrome c oxidase: Cyanide is a potent inhibitor of cytochrome c oxidase. It binds to the iron within the heme group of the enzyme, preventing the transfer of electrons to oxygen.

Analyze the impact of cytochrome c oxidase inhibition: When cytochrome c oxidase is inhibited by cyanide, the electron transport chain is disrupted, halting the flow of electrons. This prevents the establishment of the proton gradient necessary for ATP synthesis.

Conclude the overall effect on ATP production: As a result of the inhibition of the electron transport chain by cyanide, ATP production is effectively halted, leading to a cessation of energy production in the cell.
