Question:
The buffer system that helps in maintaining pH of blood between 7.26 and 7.42 is
The buffer system that helps in maintaining pH of blood between 7.26 and 7.42 is
Show Hint
Remember H$_2$CO$_3$ / HCO$_3^-$ as the primary buffer system in blood regulation.
Updated On: Jun 3, 2025
- HCN / CN$^-$
- H$_2$CO$_3$ / HCO$_3^-$
- CH$_3$COOH / CH$_3$COO$^-$
- H$_3$PO$_4$ / H$_2$PO$_4^-$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The carbonic acid (H$_2$CO$_3$) and bicarbonate (HCO$_3^-$) buffer system is the most important in maintaining the blood pH. It helps neutralize excess acids or bases in the blood.
