Question

Which one of the following statements about human sperm is correct?

• A. Acrosome has a conical point structure used for piercing and penetrating the egg resulting in fertilisation
• B. The sperm lysins in the acrosome dissolve the egg envelope facilitating fertilisation
• C. Acrosome serves as a sensory structure leading the sperm towards the ovum
• D. Acrosome serves no particular function

Answer 1

The correct option is B The sperm lysins in the acrosome dissolve the egg envelope facilitating fertilisation

The acrosome is a small pointed structure at the tip of the nucleus. It breaks down just before fertilization, releasing hydrolytic enzymes that assist in the penetration of follicle cells that surrounds the ovum, thus facilitating fertilization.
