Solution
Proteins contribute to the acid-base balance of the blood in several ways:
-
Serve as buffers that resist changes in pH: Proteins have both acidic and basic groups, so they can act as buffers to resist changes in pH. They can donate or accept protons (H+ ions) to maintain the pH of the blood.
-
Pump ions into and out of cells: Proteins in the cell membrane can transport ions into and out of cells. This helps to maintain the balance of ions in the blood, which can affect the pH.
The other two options, "Enhance formation of bicarbonate" and "Increase excretion of CO2 by the lungs", are not directly related to the role of proteins in maintaining the acid-base balance of the blood. Bicarbonate formation and CO2 excretion are primarily functions of the kidneys and lungs, respectively.

s this statement correct The role of the bicarbonate buffer system is to maintain pH in the blood, which involves the balance between carbon dioxide and bicarbonate ions in combination with water. As indicated in the blood test, the carbon dioxide is higher than the reference range, resulting in the body increasing the respiration rate to release more carbon dioxide in order to restore equilibrium. Bicarbonate mops up excess hydrogen ions and forms carbonic acid and carbon dioxide, which decreases the pH level, making the blood more acidic (Hopkins et al., 2022). By increasing the respiration rate, the body can excrete carbon dioxide, bringing the pH level back to normal.
