Acrosome reaction in sperm is triggered by:
Correct answer: B. Release of lysin
- A. Capacitation
- B. Release of lysin
- C. Influx of Na+
- D. Release of fertilizin
Explanation
The acrosome of a sperm contains enzymes, including lysin, which are involved in breaking down the protective layers surrounding the egg. The release of these enzymes from the acrosome is indeed a key trigger for the acrosome reaction. The acrosome reaction allows these enzymes to be released, enabling the sperm to penetrate the egg's protective layers.
