How can cyanide affect cellular respiration?

How does Cyanide kill you? The final stage of cellular respiration is the electron transport chain (ETC). The ETC is a series of molecules embedded in the mitochondrial membrane. The first molecule accepts protons and electrons from the products of the Krebs Cycle. read more

According to the Organisation for the Prohibition of Chemical Weapons, hydrogen cyanide inhibits metal containing enzymes necessary for cellular respiration. Cytochrome c oxidase, one of the enzymes affected by cyanide, contains iron and is responsible for the process that provides cells with energy through the use of oxygen. read more

The Cynaide molecule which dissolve in the water film(air sac) forming Cyanide ions interfere with cellular respiration, resulting in the body's tissues being unable to use oxygen .Cyanide poisoning is resulted because the cells of an organism are unable to create ATP(providing energy for respiration), primarily through the inhibition of the mitochondrial enzyme . read more

Cyanide poisoning requires cyanide ions, and these ionsmess with an important enzyme in the mitochondria of the cell,called cytochrome c oxidase. In this way, carbon monoxide preventsthe oxygen from getting to the cells, while cyanide prevents thecells from generating the energy. read more

Cyanide prevents cellular respiration leading to cell mortality. According to the Organisation for the Prohibition of Chemical Weapons, hydrogen cyanide inhibits metal containing enzymes necessary for cellular respiration. read more
