Why is cyanide such an effective poison? You might be surprised to learn that it directly interferes with cellular respiration that occurs in the mitochondria.6. Recall that the mitochondrion is sometimes called the "powerhouse" of the cell. What does this mean? Why is the mitochondrion important?it produces ATP(energy) from glucose and oxygen
Part 3: Why Do We Need Oxygen?It seems like a simple question, everyone knows you need to breathe to live. Have you ever thought about why oxygen is so important? The victims of the cyanide poisoning all had high levels of oxygen in their blood, but the poison was interfering with how the cells use that oxygen. To understand, we need to take a very close look at the structure of the mitochondrion.Inside the mitochondrion, there are several layers of membranes. In fact, these membranes resemble the membrane thatsurrounds the cell. It has a bilayer of phospholipids and embedded proteins. On the diagram above, the proteins are labeled I, II, III, IV, and Cytochrome C.The proteins in the membrane pass electrons from one to the other, this is known as the electron transport chain. The passing of these electrons allows ATP(adenosine triphosphate) to be generated. At the end of the electron transport chain, Cytochrome C passes the electron to its final acceptor, oxygen. Oxygen then binds with proteins to create water. This process is continuous in cells, with ATP constantly being generated 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 of the chain and cannot be passed to oxygen. The whole chain grinds to a halt and no ATP can be made. 7. COLORING: On the model of mitochondrion, highlight the area (arrows) that is the ELECTRON TRANSPORT CHAIN in yellow. Place an X over the protein that is inhibited by cyanide. | Color the phospholipid bilayer blue. | A special protein called ATP synthase generates ATP. Find it on the diagram and color it red.***8. What is the relationship between the ETC and oxygen?Oxygen is final destination of ETC (makes water from electrons)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 about ATP and cellular respiration, explain why cyanide is so fast acting.Blocks respiration so cellular death occurs quickly
