Q. Which one of the following statements about human sperm is correct?
A) Acrosome serves no particular function
B) Acrosome has a conical pointed structure used for piercing and penetrating the egg resulting in fertilization
C) The sperm lysins in the acrosome dissolve the egg envelope facilitating fertilization
D) Acrosome serves as a sensory structure leading the sperm towards the ovum
Explanation
[Solution from source] The acrosome is a cap-like structure that comes from the Golgi apparatus. It contains hydrolytic enzymes (sperm lysins) that dissolve the egg's coverings so the sperm can enter. It works chemically, by enzymes, not by mechanically piercing the egg. Answer (3).
