Explain how Diamox, drug that inhibits carbonic anhydrase, could help people function at high altitudes, and indicate the limitations of its effectiveness
What will be an ideal response?
Inhibiting carbonic anhydrase will cause CO2 to build up in the blood. This will trigger the brain and carotid sensors to trigger a faster rate of breathing. This in turn will increase the oxygen supply to the tissues. However, the drug does not improve physical performance (although it may alleviate symptoms of altitude sickness that could make a person less effective) and it will not help people who are at such a high altitude that they can't get enough oxygen even if they breathe faster.
