Sperms produce an enzymatic chemical for dissolving the egg coverings, is called :

Options

A. Hyaluronic acid
B. Hyaluronidase
C. Androgamone
D. Diastase

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks for the name of the enzymatic chemical produced by sperm that helps in dissolving the egg coverings.

2. **Identifying the Egg Coverings:**
The ovum (egg) is surrounded by protective layers, typically consisting of multiple membranes that need to be penetrated for fertilization to occur.

3. **Role of Sperm in Fertilization:**
Sperm must penetrate these layers to fertilize the ovum. This penetration is facilitated by specific enzymes that can degrade the protective layers.

4. **Location of the Enzymes:**
The enzymes responsible for dissolving the egg coverings are stored in a part of the sperm called the acrosome, which is located in the head of the sperm.

5. **Key Enzymes Identified:**
The two main enzymes mentioned that assist in this process are:
- **Hyaluronidase:** This enzyme helps in breaking down the hyaluronic acid that forms part of the egg's protective layers.
- **Acrosine:** This enzyme also plays a role in degrading the membranes surrounding the ovum.

6. **Conclusion:**
Based on the information provided, the correct answer to the question is **Hyaluronidase**, as it is specifically mentioned as an enzyme that dissolves the egg coverings.

**Final Answer:**
The enzymatic chemical produced by sperm for dissolving the egg coverings is called **Hyaluronidase**.
