Answer
Cytochromes are reduction-oxidation carriers with a central atom of iron. In the Electron Transport Chain, the cytochromes help to transport electrons to oxygen. When one of the cytochromes is inhibited, as by cyanide, the mitochondria can't use the oxygen and subsequently, cannot produce ATP. Once all of the body's ATP stores are depleted, cells begin to die and then the individual dies
Work Step by Step
Cyanide binds to cytochromes blocking their function which leads to cell death from an inability to produce further ATP.
