Hydrolysing enzymes are present in

Options

A. Nucleoplasm, peroxisomes
B. Lysosomes, peroxisomes
C. Glyoxysomes, nucleoplasm
D. Lysosomes, nucleoplasm.

Answer

### Step-by-Step Solution:

1. **Understanding Hydrolyzing Enzymes**: Hydrolyzing enzymes are enzymes that catalyze the hydrolysis reaction, which involves the breakdown of complex molecules into simpler ones by the addition of water.

2. **Identifying Organelles**: The question asks where these hydrolyzing enzymes are present. The options given are:
- Nucleoplasm
- Peroxisome
- Lysosome
- Glyoxysome

3. **Analyzing Each Option**:
- **Nucleoplasm**: This is the viscous fluid inside the nucleus. It does not contain hydrolyzing enzymes. Therefore, this option is incorrect.
- **Peroxisome**: This organelle is involved in various metabolic processes, including the breakdown of fatty acids and detoxification. It contains some hydrolytic enzymes, such as catalase, which breaks down hydrogen peroxide. This option is partially correct.
- **Lysosome**: Known as the "suicidal bag of the cell," lysosomes contain a variety of hydrolytic enzymes that are crucial for breaking down waste materials and cellular debris. This is the primary organelle associated with hydrolyzing enzymes, making this option correct.
- **Glyoxysome**: These are specialized peroxisomes found in plants, primarily involved in fatty acid metabolism. They may contain some hydrolytic enzymes, but they are not the main site for hydrolytic activity.

4. **Conclusion**: The organelle that is primarily known for containing hydrolyzing enzymes is the **Lysosome**. While peroxisomes also contain some hydrolytic enzymes, lysosomes are the main organelles associated with hydrolysis.

### Final Answer:
Hydrolyzing enzymes are primarily present in **Lysosomes**.
