Interaction of cyanide and nitric oxide with cytochrome c …
Cyanide is a potent cytochrome c oxidase (COX, a.k.a. Complex IV) inhibitor. As such, cyanide poisoning is a form of histotoxic hypoxia, because it interferes with oxidative phosphorylation. Specifically, cyanide binds to the heme a3-CuB binuclear center of COX (and thus is a non-competitive inhibitor of it). This … See more Cyanide poisoning is poisoning that results from exposure to any of a number of forms of cyanide. Early symptoms include headache, dizziness, fast heart rate, shortness of breath, and vomiting. This phase may then be … See more Acute exposure If hydrogen cyanide is inhaled, it can cause a coma with seizures, apnea, and cardiac arrest, with death following in a matter of seconds. At lower doses, loss of consciousness may be preceded by general weakness, … See more Lactate is produced by anaerobic glycolysis when oxygen concentration becomes too low for the normal aerobic respiration pathway. Cyanide poisoning inhibits aerobic respiration … See more Fires The República Cromañón nightclub fire broke out in Buenos Aires, Argentina on 30 December 2004, killing 194 people and leaving at least 1,492 injured.

The last typically occurs … See more Decontamination Decontamination of people exposed to hydrogen cyanide gas only requires removal of the … See more Cobinamide is the final compound in the biosynthesis of cobalamin. It has greater affinity for the cyanide than cobalamin itself, which suggests that it could be a better option for emergency treatment. See more WebNov 14, 2024 · When people ingest cyanide ion, the cyanide binds strongly to the enzyme that transfers electrons from cytochrome c to oxygen. This blocks the enzyme from functioning. Why does this cause death so quickly? Cyanide poisoning victims often feel like they are suffocating and breathe deeply and rapidly before death. Why do you think they … igor amigud physicians
