Which type of enzyme occurs in lysosome?

Options

A. Lyase
B. Ligase
C. Hydrolase
D. Transferase

Answer

### Step-by-Step Solution:

1. **Understanding Lysosomes**:
- Lysosomes are membrane-bound organelles found in eukaryotic cells. They are often referred to as the "suicidal bags" of the cell because they contain enzymes that can break down various biomolecules.

2. **Function of Lysosomes**:
- The primary function of lysosomes is to digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria. They play a crucial role in cellular digestion and recycling.

3. **Types of Enzymes in Lysosomes**:
- Lysosomes contain a variety of enzymes that facilitate the breakdown of macromolecules. The key types of enzymes found in lysosomes include:
- **Hydrolases**: These enzymes catalyze the hydrolysis of chemical bonds, breaking down proteins, nucleic acids, carbohydrates, and lipids.
- Other types of enzymes such as lyases, ligases, and transferases are not primarily involved in the digestion process within lysosomes.

4. **Identifying the Correct Answer**:
- Among the options provided (lyase, ligase, hydrolase, and transferase), the enzyme that is specifically known to occur in lysosomes and is responsible for breaking down biomolecules is **hydrolase**.

5. **Conclusion**:
- Therefore, the correct answer to the question "Which type of enzyme occurs in lysosome?" is **hydrolase**.
