Which one of the following statements about human sperm is correct?a)...
Acrosome a small pointed structure at the tip of nucleus. It breaks down just before fertilization, releasing hydrolytic enzymes that assist penetration between follicle cells that surrounds the ovum, thus facilitating fertilization.

Which one of the following statements about human sperm is correct?a)...
Statement: The sperm lysis in the acrosome dissolve the egg envelope facilitating fertilisation.
Explanation:
The acrosome is a specialized structure present at the anterior end of the sperm head. It is derived from the Golgi apparatus and contains enzymes that play a crucial role in fertilization. The correct statement about human sperm is option 'B' - The sperm lysis in the acrosome dissolve the egg envelope facilitating fertilisation.
Acrosomal Reaction:
The acrosomal reaction is a series of biochemical events that occur when the sperm comes into contact with the egg. It involves the release of enzymes from the acrosome to dissolve the outer layer of the egg called the zona pellucida. This process is essential for the sperm to penetrate the egg and fertilize it.
Function of Acrosome:
The acrosome serves as a reservoir for enzymes that are required for the fertilization process. The enzymes present in the acrosome include hyaluronidase, acrosin, and neuraminidase. These enzymes help in breaking down the glycoproteins of the zona pellucida, which surround the egg.
Acrosome Reaction:
The acrosome reaction is triggered when the sperm reaches the zona pellucida. The binding of specific proteins on the sperm surface to the zona pellucida initiates the acrosome reaction. Once triggered, the enzymes are released from the acrosome, leading to the dissolution of the egg envelope.
Role in Fertilization:
The dissolution of the egg envelope by the enzymes released from the acrosome allows the sperm to penetrate the egg. This process is crucial for the fusion of the sperm and egg membranes, leading to fertilization. Without the acrosome and its enzymes, the sperm would not be able to overcome the barriers presented by the egg envelope.
Conclusion:
In conclusion, the correct statement about human sperm is that the sperm lysis in the acrosome dissolve the egg envelope facilitating fertilization. The acrosome plays a vital role in releasing enzymes that break down the zona pellucida, allowing the sperm to penetrate the egg and fertilize it.
