Acrosome is filled with which of the following?
Correct answer: C. Digestive enzymes
- A. Lipids
- B. Hormones
- C. Digestive enzymes
- D. All of these
Explanation
The acrosome is a structure located at the tip of the sperm cell's head, and it contains hydrolytic enzymes. These enzymes play a crucial role during fertilization. The primary enzyme found in the acrosome is called hyaluronidase. Hyaluronidase helps the sperm penetrate the protective layers surrounding the egg, particularly the zona pellucida. The zona pellucida is a glycoprotein layer surrounding the egg cell. The hydrolytic enzymes released from the acrosome help to break down this protective layer, allowing the sperm to reach and bind to the egg.
