Cyanide poisoning causes death in seconds because
-
- It denatures enzymes of the heart/muscle
- It breaks the electron transport chain
- It causes Lysis of red blood cells.
- It causes cardiac arrest
- It denatures enzymes of the heart/muscle
Correct Option: D
Cyanide poisoning occurs on exposure to a compound that produces cyanide ions when dissolved in water. The cyanide ion halts cellular respiration by inhibiting an enzyme in the mitochondria called cytochrome c oxidase. If cyanide is inhaled it causes a coma with seizures, apnea, and cardiac arrest, with death following in a matter of seconds.
