1.	Question : Acrosomal reaction of the sperm occurs due to
Answer» Its contact with zona pellucida of the ova Reactions within the uterine environment of the female Reactions within the epididymal environment of the male Androgens prouced in the uterus Solution :One sperm among three glycoprotein works as a consumer and connects with supplementary molecule located on the head surface of sperm cell. The connection of head sperm cell with consumer molecule `ZP_(3)` induces acrosome of sperm cell to release HYDROLYTIC enzyme (spermlycin) The lycin released from sperm possesses following (i) Hyleuronedase that performs hydrolysis of hyleuronic acid of cell of FOLLICLE. (ii) Enzyme entering in corona, induces HYDROYSIS of stroma parts of radiate corona surrounded by secondary oocyte (iii) Zona lycin induces digestion of Acrosin zona pelusida. Above all enzymes dissolve corona radiate and zona pellusida and reach sperm till cytoplasm MEMBRANE of ovum. The effect of above changes occurring in head of sperm is called PROCESS of acrosome.
