Drete testis
6. Which one of the following statements about human sperm is correct?
(AIPMT 2010)

fertilisation
C. Acrosome serves as a sensory structure leading the sperm towards the on
D. Aerosome serves no particular function
7. The extra embryonic membranes of the mammalian embryo are derived from
(AIPMT 1994)​

Answer 1

Explanation:

5- Capacitation occurs in female reproductive tract

6- Acrosomes contain digestive enzymes like hyaluronidase and lysins, which helps in breaking down the outer membrane of the ovum called as the zona pellucida, allowing the haploid nucleus in the sperm cell to join the haploid nucleus in the ovum, thus enabling fertilization. Hence, the correct answer is option B

7- The extra embryonic membranes of mammalian embryo are derived from trophoblast.
