Answer to Question 1

A

Answer to Question 2

Bicarbonate and carbonic acid work together to maintain a constant blood pH. Carbonic acid is formed when carbon dioxide, formed from metabolic processes, dissolves in the blood. The carbonic acid can then dissociate into protons and bicarbonate ions. As carbonic acid levels rise, and bicarbonate ions decrease, the pH levels drop. In order to raise the blood pH, respiration rates increase in the lungs, and carbon dioxide is exhaled. This in turn raises the blood pH levels by removing carbonic acid from the blood. Similarly, when carbonic acid levels decrease and bicarbonate ions increase, respiration rates decrease, preventing the loss of carbon dioxide, and the levels of carbonic acid are retained in the blood. Additionally, excess bicarbonate is excreted in the urine or reabsorbed by the kidney when the pH levels rise and fall, respectively.
