Answer 1

Carbonic anhydrase significantly increases the conversion of CO2 to HCO3- in the blood, crucial for the bicarbonate buffer system and respiratory function.

Step-by-step explanation:

Carbonic anhydrase greatly increases the interconversion of CO2 and HCO3- in the blood. This enzyme accelerates the conversion of carbon dioxide and water into carbonic acid (H₂CO₃), which then quickly dissociates into bicarbonate (HCO3-) and hydrogen ions (H+). The bicarbonate buffer system is crucial for maintaining blood pH levels and facilitating CO2 transport in the blood. As such, carbonic anhydrase is fundamental in the regulation of the body's acid-base balance and the respiratory function.
