Question

The breakage of the membrane surrounding the acrosome in a mammalian sperm is

• A. Activation
• B. Cavitation
• C. Agglutination
• D. Capacitation

Answer 1

The correct option is D Capacitation

Capacitation is the phenomenon of sperm activation by which the sperm develop the ability to fertilize ova. 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 become active to penetrate the egg. This phenomenon of sperm activation in mammals is known as capacitation.

So, the correct answer is 'Capacitation'
