Fertilisin protein is present in:
Fertilisin protein is present in:
Open in App
Solution
The correct option is B Mature oocyte
Fertilisin is a chemical substance found on the surface of the mature oocyte. This reacts with antifertilisin molecule present on the surface of the sperms. The interaction of these two chemicals helps in the recognition of the male and female gametes of the same species.
Polar bodies are formed during the meiotic divisions of the oocyte. The primary oocyte undergoes meiosis I to form a secondary oocyte and first polar body. The secondary oocyte undergoes meiosis II to form ovum (or ootid) and a second polar body. The polar bodies disintegrate. They don’t carry any chemical substances.
Acrosome is found at the anterior most portion of the sperm and is rich in hydrolytic enzymes like hyaluronidase and acrosin.
The middle piece of the sperms contains the mitochondria which provide the energy for the transportation of sperms.
