Acrosome reaction in sperm is triggered by

1. capacitation
2. release of lysin

Correct answer: capacitation

Capacitation is the functional maturation of sperm in the female reproductive tract that enables the acrosome reaction. Without capacitation, the sperm cannot properly undergo the membrane changes needed to release acrosomal enzymes.
