Question

Identify the enzyme that catalyses the reaction of CO₂ with water in huma body.

Options

• Carbonic anhydrase

• Ferroxidase

• Nitrogenase

• Catalase

Answer 1

Carbonic anhydrase

Explanation:

In the human body, the carbonic anhydrase enzyme catalyses the reaction of CO₂ with water. It catalyses a reaction that converts CO₂ and water into carbonic acid, which dissociates into protons and bicarbonate ions. It is found in red blood cells.

\[\ce{CO2 + H2O ->[Carbonic anhydrase] H2CO3}\]

CO₂ is transported from tissues to the lungs through the bloodstream.
