Question

Quizplus · Accepted Answer

Cyanide inhibits cytochrome c oxidase, which is a critical enzyme in the electron transport chain of mitochondria. This inhibition causes electron transport to stop, which leads to a decrease in the proton gradient across the inner mitochondrial membrane. As a result, ATP synthesis decreases because ATP synthase depends on the proton gradient for its function.
