cant be D since cyanide poisoning is treated with an antidote if given rapidly.. (nitrites)
E i think is uncouplers??? Since the electron transport chain is coupled to oxidative phosphorylation, their activites will rise and fall together, an inhibition in any step will affect the entire system and therefore reduce the cytochromes??? sao help!
