The enzyme called Marker enzyme in lysosome is

Options

A. acid phosphatase
B. peroxidase
C. hyaluronidase
D. catalase

Answer

**Step-by-Step Solution:**

1. **Understanding Lysosomes**: Lysosomes are cell organelles that contain enzymes responsible for breaking down waste materials and cellular debris. They are often referred to as the "digestive system" of the cell.

2. **Origin of Lysosomes**: Lysosomes originate from the Golgi apparatus, which is involved in the packaging and distribution of proteins and lipids within the cell.

3. **Enzymatic Composition**: Lysosomes contain approximately 60 different hydrolytic enzymes. These enzymes are crucial for the digestion of various biomolecules, including lipids (digested by lipases) and nucleic acids (digested by nucleases).

4. **Identifying Marker Enzymes**: Marker enzymes are specific enzymes that are used to identify a particular organelle. In the case of lysosomes, the marker enzyme is acid phosphatase.

5. **Function of Acid Phosphatase**: Acid phosphatase plays a significant role in hydrolyzing organic phosphates, which is an important function for the lysosomal activity.

6. **Eliminating Other Options**:
- Peroxidase and catalase are enzymes found in peroxisomes, not lysosomes.
- Hyaluronidase is also not a marker enzyme for lysosomes; it is associated with other functions in the body.

7. **Conclusion**: Therefore, the enzyme that is considered a marker enzyme in lysosomes is **acid phosphatase**.

**Final Answer**: The enzyme called the marker enzyme in lysosome is **acid phosphatase**.
