Refer to the given reactin.
`{:(C_(12)H_(22)O_(11)+H_(2)O overset(Enzyme A)to 2C_(6)H_(12)O_(6)),("Maltose"" ""Glucose"):}`
Enzyme A used in the reaction, belongs to which class of enzymes ?

Options

A. Dehydrogenases
B. Transferases
C. Hydrolases
D. Lyases

Explanation

To determine the class of enzyme A used in the reaction where maltose is converted into glucose, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reaction**: The given reaction shows maltose (C₁₂H₂₂O₁₁) being hydrolyzed into two molecules of glucose (C₆H₁₂O₆) in the presence of water (H₂O) and enzyme A.

2. **Understand the Role of Enzyme A**: Enzyme A facilitates the breakdown of maltose into glucose. This process involves the addition of water, which indicates a hydrolytic reaction.

3. **Classify the Enzyme**: Enzymes are classified into six main categories based on the type of reaction they catalyze:
- Oxidoreductases: Catalyze oxidation-reduction reactions.
- Transferases: Transfer functional groups from one molecule to another.
- Hydrolases: Catalyze the hydrolysis of various bonds (e.g., peptide bonds, glycosidic bonds).
- Lyases: Add or remove groups to form double bonds.
- Isomerases: Catalyze the rearrangement of molecular structures.
- Ligases: Catalyze the joining of two molecules with the use of ATP.

4. **Identify the Correct Class**: Since enzyme A is involved in the hydrolysis of maltose into glucose, it falls under the category of hydrolases. Hydrolases are responsible for breaking down compounds by adding water.

5. **Conclusion**: Therefore, enzyme A, which is maltase in this reaction, belongs to the class of enzymes known as hydrolases.

### Final Answer:
Enzyme A belongs to the class of enzymes called **hydrolases**.
