Cyanide is a potent cytochrome c oxidase (COX, a.k.a. Complex IV) inhibitor, causing asphyxiation of cells. As such, cyanide poisoning is a form of histotoxic hypoxia, because it interferes with the ability of cells to take or use oxygen via oxidative phosphorylation. [25] : 1475.

[5] [6] [15] It is the most common of the cardiovascular ...
