Is bicarbonate (HCO[tex]\(_3^-\)[/tex]) the most prevalent anion in extracellular fluid?

A. False
B. True



Answer :

Final answer:

Bicarbonate (HCO3) is vital for maintaining acid-base balance in the body through processes like the bicarbonate buffer system and the chloride shift.


Explanation:

Bicarbonate (HCO3) is a crucial component of the bicarbonate buffer system in the blood, playing a key role in maintaining the body's acid-base balance. It is produced through the dissociation of carbonic acid and is involved in regulating pH levels by absorbing carbon dioxide.

In the blood, bicarbonate ions (HCO3) are transported between red blood cells and plasma through processes like the chloride shift, ensuring the efficient exchange of ions to regulate blood pH and facilitate the elimination of carbon dioxide through exhalation.

The enzymatic action of carbonic anhydrase is essential in catalyzing the conversion of carbon dioxide to bicarbonate ions, highlighting the intricate mechanisms through which bicarbonate contributes to the body's acid-base balance.
