The function of hyaluronidase enzyme is:
Correct answer: A. Penetration of the sperm into the Ovum
- A. Penetration of the sperm into the Ovum
- B. Entrance of the sperm into the vagina tube
- C. Entrance of the sperm into the fallopian
- D. Inactivation of sperms after their failure to fertilize ovum
Explanation
The process of fusion of a sperm with the ovum is called fertilization. Before fusion of a spermatozoan with the egg, the spermatozoan has to penetrate a few barriers, the egg membranes, which cover the egg. The secretions of the acrosome help the sperm to enter into the cytoplasm of the ovum through the zona pellucida and the plasma membrane. All the chemicals are contained in the acrosome located at the tip of the sperm head and are collectively called sperm lysins. [e.g., CPE, Zonalysin, Hyaluronidase]. The function of hyaluronidase is to puncture the vitelline membrane of an egg.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
