Question
a) 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.
Explanation / Answer
When humans breathes, consuming oxygen in the air to perform this process uses glucose as fuel , the product of the process of respiration is carbon dioxide and water.
As stated in the title body dioxio strikes a balance between carbon and water which is partially joined to form carbonic acid .
When a person is at high altitude the partial pressure of oxygen in the body decreases accelerating the process of breathing to capture more oxygen , which accelerates the production of carbon dioxide and water, generating an increase of carbonic acid in the blood, the accumulation of carbonic acid acidosis provoked a blood acidosis ........ when a buffer system carbonic acid - acid carbonate generate action to restore the pH balance in the blood.
