Acrosome reaction in sperm is triggered by:
Acrosome reaction in sperm is triggered by:
Show Hint
Capacitation is like âremoving the safety lockâ so the acrosome âgunâ can fire.

- Release of Lysin
- Determination
- Capacitation
- Compaction
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
The acrosome reaction allows the sperm to penetrate the egg's protective layers.
Step 2: Meaning
Before the acrosome reaction, the sperm must undergo functional maturation in the female tract.
Step 3: Analysis
This maturation is called capacitation. It involves removal of cholesterol and glycoproteins from the sperm membrane, making it capable of the acrosome reaction.
Step 4: Conclusion
Capacitation is the physiological prerequisite that triggers readiness for the acrosome reaction.
Final Answer: (C)
