State humans unaccustomed to high altitudes tend to breathe

Reference no: EM13192882

The principle buffer system in human blood involves the weak acid, carbonic acid (H2CO3), and its conjugate base, bicarbonate ion (HCO3-),
H2CO3(aq) + H2O(l) » H3O+(aq) + HCO3-(aq)

An equilibrium between carbonic acid, carbon dioxide and water is also established,

H2CO3(aq) » CO2(g) + H2O(l)

Humans unaccustomed to high altitudes tend to breathe much more rapidly (at least initially) because the partial pressure of O2(g) in air is much lower compared with that at low altitudes. Will rapid breathing at high altitudes tend to produce: (1) blood acidosis (blood pH lower than normal) or (2) blood alkalosis (blood pH higher than normal)? Explain your reasoning.
