Question

The fertilization membrane during fertilization is synthesized by

• A. Mitochondria
• B. Golgi bodies
• C. Acid mucopolysaccharides of cortical granules
• D. All of the above

Answer 1

The correct option is C Acid mucopolysaccharides of cortical granules

The vitelline membrane is adjacent to the outer surface of the plasma membrane of ovum. When the sperm fuses with the ovum, then series of signal transduction takes place which results in the deposition of several substances (like acid mucopolysaccharides) on this vitelline membrane through exocytosis of cortical granules and this transforms the vitelline membrane to a hard layer called as the fertilization membrane.

Thus, the correct answer is option C.
