If the cyanide gas was released outdoors, move away from the area where it was released. How does cyanide affect ATP production? How does cyanide cause weak muscles? Acute cyanide toxicity is attributed to inhibition of cytochrome c oxidase (CcOX), the oxygen-reducing component of mitochondrial electron transport; however, the mitochondrial action of cyanide is complex and not completely understood. surfaces, cyanide compounds will form hydrogen sulfide and evaporate. As a result, intracellular oxygen utilization ceases. Death from poisoning usually results from respiratory or heart failure. A person exposed to cyanide may have cherry-red skin from high oxygen levels or dark or blue coloring, from Prussian blue (iron-binding to the cyanide ion). Biology. Netto AB, Netto CM, Mahadevan A, Taly AB, Agadi JB. Sodium cyanide (NaCN), potassium cyanide (KCN), hydrogen cyanide (HCN), and cyanogen chloride (CNCl) are lethal, but thousands of compounds called nitriles contain the cyanide group yet aren't as toxic.
