Vedclass · Answer

(B) Carbon dioxide $(CO_2)$ reacts with water $(H_2O)$ in the presence of the enzyme carbonic anhydrase to form carbonic acid $(H_2CO_3)$.This reaction is reversible: $CO_2 + H_2O \rightleftharpoons H_2CO_3 \rightleftharpoons H^+ + HCO_3^-$.In the blood, hemoglobin acts as a buffer. When $H^+$ ions are produced, they are buffered by hemoglobin, preventing a significant rise in acidity.However, the question refers to the specific role of ions in maintaining acid-base balance. Potassium ions $(K^+)$ play a crucial role in the chloride shift (Hamburger phenomenon) and the exchange of ions across the erythrocyte membrane to maintain electrical neutrality, which helps in regulating the $pH$ and preventing the accumulation of excess carbonic acid in the plasma.

The concentration of carbonic acid does not increase in the blood due to the presence of which of the following?
