The Science of Cyanide Poisoning
Cyanide disrupts cellular respiration by inhibiting cytochrome c oxidase, halting ATP production and causing tissue asphyxiation despite normal oxygen levels, leading to rapid systemic failure.
2.1 How Cyanide Affects Cellular Respiration
Cyanide inhibits cytochrome c oxidase, a key enzyme in the electron transport chain, disrupting ATP synthesis. This halts cellular respiration, causing tissues to asphyxiate despite normal oxygen levels, leading to rapid organ failure and death.
2.2 The Role of Oxygen in Tissue Asphyxiation
Oxygen is present in the blood but cannot be utilized due to cyanide’s blockage of cellular respiration. This leads to tissue asphyxiation, as cells cannot produce ATP, causing rapid organ failure. The Chicago Cyanide Murders highlighted how cyanide disrupts oxygen utilization, resulting in suffocation at the cellular level despite normal oxygen levels in the blood.
