Summary Introduction
To explain: The reason that the cyanide poisoning starts with the same symptoms as altitude sickness.
Concept introduction:
At a higher altitude, oxygen concentration decreases in the air. It creates shortness of breath due to the low oxygen concentration. Cyanide binds to cytochrome c oxidase that prevents the reduction of the oxygen molecule as it stops the transfer of electrons in the final steps of electron transfer chain.
