- spermiogenesis
- capacitation
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The secretions of the female genital tract remove coating substances deposited on the surface of the sperms particularly those on the acrosome. Thus, the receptor sites on the acrosome are exposed and sperm becomes active to penetrate the egg. This phenomenon of sperm activation in mammals is known as capacitation.
