What is Cyanide and How Does it Affect the Cell?
Deanna Dailey
What is Cyanide• Chemical Formula: CN-
• Mass of 26.007 g/mol• Soluble in water• Lighter than air• Mainly a gas, but can be a liquid under 78
degrees F.• Tastes or smells like bitter almonds• Forms salts with Alkali metals. (Na, K, H)• Highly flammable
How does it kill?
• It affects a step in cellular respiration.• Electron chain: inhibits the electron transfer to oxygen
• It binds to the cytochrome oxidese so the so the oxygen can’t make ATP• No free energy to do anything cellular related
• No amount of breathing will help, the oxygen cannot be used.
• With hydrogen cyanide, the victim goes into cardiac arrest after 4 min.
