How does cyanide poisoning result in the decrease of ATP production?
a. Cyanide permanently oxidizes cytochrome a3, preventing other components to change into the reduced state. This causes the proton gradient to break down, stopping ATP synthesis. b. Cyanide uncouples the proton gradient from the process of ATP synthesis. c. Cyanide permanently reduces cytochrome a3, preventing other components to change into the oxidized state. This causes the proton gradient to break down, stopping ATP synthesis. d. Cyanide permanently binds to oxygen, preventing its use as the final electron acceptor.
