and oxygen being used as the final electron acceptor. Cyanide inhibits cytochrome C, preventing the last protein from doing its job. The electron stops at the end ofthe chain and cannot be passed to oxygen. The whole chain grinds to a halt and no ATP can be made. Click on the video linkto see how cyanide disrupts ATP synthesis.7.

(This is a protein that generates ATP.) 8. What is the relationship between the ETC and oxygen?
The relationship between the two is that oxygen is used as an electron acceptor in the electron transport chain, accepting the electrons from the electron carriers like NADH and FADH2.9. Cyanide is an extremely fast acting poison. In fact, it was developed as a suicide pill (called L-pill) during World War II so that British and American spies could avoid being captured alive. Given what you know aboutATP and cellular respiration, explain why cyanide is so fast acting.Cyanide stops ATP producing and if no energy is being produced, you die.10. Given what you know about cyanide poisoning, do you think that giving a person oxygen would be an effective treatment? Why or why not?No, because energy and oxygen are 2 different things.
