Which of the following enzyme digests other enzymes-

Options

A. Dehydrogenases
B. Lipases
C. Peptidases
D. Aldolases

Explanation

To determine which enzyme digests other enzymes, we can analyze the options given: dehydrogenases, lipases, peptidases, and aldolases.

### Step-by-Step Solution:

1. **Understanding Enzymes**: Enzymes are biological catalysts that speed up chemical reactions in the body. They are primarily proteins made up of amino acids linked by peptide bonds.

2. **Analyzing the Options**:
- **Dehydrogenases**: These enzymes are involved in oxidation-reduction reactions, primarily facilitating the removal of hydrogen from substrates.
- **Lipases**: These enzymes break down lipids (fats) into fatty acids and glycerol.
- **Peptidases**: These enzymes are responsible for breaking peptide bonds between amino acids, effectively digesting proteins.
- **Aldolases**: These enzymes play a role in glycolysis, converting specific substrates into other molecules.

3. **Identifying the Correct Enzyme**: Since the question asks for the enzyme that digests other enzymes, we focus on the function of peptidases. Peptidases break down proteins into smaller peptides or amino acids, which means they can also break down enzymes since enzymes are proteins.

4. **Conclusion**: The enzyme that digests other enzymes is **peptidases**.

### Final Answer:
The correct answer is **peptidases** (option 3).
