Name the hydrolytic enzyme secreted by the acrosome.

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Acrosome**: The acrosome is a specialized structure located at the tip of the sperm cell. It plays a crucial role in the fertilization process.

2. **Identifying the Enzymes**: The acrosome contains several hydrolytic enzymes that are essential for the sperm to penetrate the protective layers surrounding the ovum (egg).

3. **Key Hydrolytic Enzyme**: The primary hydrolytic enzyme secreted by the acrosome is **Hyaluronidase**.

4. **Function of Hyaluronidase**: The main function of Hyaluronidase is to break down the hyaluronic acid that forms part of the extracellular matrix surrounding the ovum. This action helps the sperm to navigate through the barriers like the Zona Pellucida and the Corona Radiata.

5. **Fertilization Process**: Once the sperm successfully penetrates these layers, fertilization can occur, leading to the fusion of the sperm and egg.

6. **Conclusion**: Therefore, the hydrolytic enzyme secreted by the acrosome is **Hyaluronidase**.
