You are now convinced that you know the cause of death for these victims and quickly report it back to the police as this is a
very dangerous situation. You suspect cyanide because it
irreversibly binds to cytochrome c oxidase (CcOx) of the
electron transport chain and prevents the transfer of electrons
to oxygen, the final electon acceptor.
Why does cyanide have a negative affect on the electron
transport chain? Explain why the patients died of lack of. oxygen
while their blood oxygen levels were normal.
