The higher the altitude, the lower the oxygen level in air. Climbers of very tall mountains risk altitude sickness, which is an illness characterized by shortness of breath, weakness, dizziness, and confusion. The early symptoms of cyanide poisoning are the same as those for altitude sickness. Cyanide binds tightly to cytochrome c oxidase, the protein that reduces oxygen molecules in the final step of mitochondrial electron transfer chains. Cytochrome c oxidase with bound cyanide can no longer transfer electrons. Explain why cyanide poisoning starts with the same symptoms as altitude sickness.
