Questions and Answers

What is the role of hyaluronidase in fertilization?

  • Dissolving the zona pellucida of the ovum
  • Binding specifically with receptor proteins in the zona pellucida
  • Opening pathways between granulosa cells for sperm to reach the ovum (correct)
  • Stimulating the Sertoli cells for germ cell activity

    • What happens within minutes after the sperm reaches the zona pellucida of the ovum?

  • The sperm head fuses with the oocyte cell membrane
  • The genetic material of the sperm and oocyte combine to form a new cell genome
  • The entire acrosome dissolves and releases all acrosomal enzymes (correct)
  • The Sertoli cells are stimulated for germ cell activity

    • What is the function of proteolytic enzymes in fertilization?

  • Breaking down granulosa cell layers and dissolving the zona pellucida (correct)
  • Stimulating Sertoli cells for germ cell activity
  • Opening pathways between granulosa cells for sperm to reach the ovum
  • Binding specifically with receptor proteins in the zona pellucida
