Why cyanide is deadly

What kind of poisons? Why Is It Deadly?

In short, the cyanide ion CN- (minus) disrupts the electron transport system in mitochondria with energy production organs in cells. Cyanide ion is found in mitochondria and in the electron transport system of oxygenation; The cytochrome C, which carries electrons to oxygen, clings to the iron atom in oxiddase. Through this holding, cyanide pretends to be an imversive enzyme suppressor, preventing cytochrome C oxidase from performing its task. Mitochondria, whose ability to use oxygen is lost, cannot produce adenocein triphosphat (ATP), an energy molecule. In other words, cyanide prevents cells from using the oxygen necessary for energy production. As a result, cells in tissues that need this type of energy, such as heart muscle cells and nerve cells, cannot meet the energy needs and rapid cell deaths begin. When cell deaths reach a high enough number, the living form loses its life.

Chronic toxic effects may occur on the central nervous system and pituitary gland if cyanide is exposed to cyanide for long periods of time in doses above 11 mg/m3, which is too low to show stimulating acute symptoms, but above the occupational exposure limit. These effects have been reported in metal plating workers made with cyanide.

In the form of hydrogen cyanide or synanogen chloride, 50 out of every 100 people exposed to cyanide gas at levels of 2.5-5 mg • dak / cubic meter and 11 mg • dak / cubic meter are expected to die. The lethal dose of sodium cyanide and potassium cyanide in the digestive tract is up to 100-200 milligrams. In such exposure, death occurs within 10 minutes.

With humans, the ability to be exposed to cyanide…..
