Write the chemical reaction catalysed by the zinc enzyme carbonic anhydrase.

Explanation

**Step-by-Step Text Solution:**

1. **Identify the Enzyme**: The enzyme in question is carbonic anhydrase, which is classified as a metalloenzyme due to the presence of zinc in its active site.

2. **Understand the Function**: Carbonic anhydrase catalyzes the reversible reaction between carbon dioxide (CO₂) and carbonic acid (H₂CO₃). This means it facilitates the conversion of these two substances back and forth.

3. **Write the Chemical Reaction**: The chemical reaction catalyzed by carbonic anhydrase can be represented as follows:
\[
