Question

question 14 (1 point) cyanide poisoning occurs because cyanide binds cytochrome oxidase, preventing it from transferring electrons to the final electron acceptor of the mitochondrial electron transport chain. what is that acceptor molecule? co2 atp o2 nadp

Explanation:

In the mitochondrial electron - transport chain, oxygen ($O_2$) is the final electron acceptor. When electrons reach the end of the electron - transport chain, they combine with oxygen and protons to form water. Cyanide inhibits this process by binding to cytochrome oxidase and preventing electron transfer to oxygen.

Answer:

C. O2
