Acrosome Reaction in Sea Urchin

  • Опубликовано: 29 окт 2024
  • During fertilization, a sperm must first fuse with the plasma membrane and then penetrate the female egg cell in order to fertilize it. Fusing to the egg cell usually causes little problem, whereas penetrating through the egg's hard shell or extracellular matrix can present more of a problem to the sperm. Therefore, sperm cells go through a process known as the acrosome reaction which is the reaction that occurs in the acrosome of the sperm as it approaches the egg. The acrosome is a cap-like structure over the anterior half of the sperm's head.
    In some echinoderms, including starfish and sea urchins, a major portion of the exposed acrosomal content contains a protein that temporarily holds the sperm on the egg's surface
    Bindin is an insoluble protein coating the sperm acrosome process and mediating the adhesion of sperm to sea urchin eggs.

    at 1:46 I said "it triggers the fusion of acrosomal membrane with sperm cell".
    Actually it is "it triggers the fusion of acrosomal membrane with egg cell"

      In the Ninth edition of Gilbert it mentions the fusion of acrosomal membrane with sperm cell but thank you sir for your further clarification on this. And thank you sir for your awesome contribution to learners.

      Your request is my work and stands at top in my priority list ,
      but the next two videos are already in progress which will occupy the dates upto 15th June.
      Then surely i will consider making that video
      thanks

    During acrosomal reaction there occur...fusion of acrosomal membrane and egg plasma membrane?

  • @ankanmaiti5962
    @ankanmaiti5962 5 месяцев назад

    Sulphate containg polysaccharides are present on egg jelly not on egg surface. Other wise it's ok

  • @DD-tr3bf

    Sir at 1.46 you said "it triggers the fusion of acrosomal membrane with sperm cell".
    Don't you think it should be "it triggers the fusion of acrosomal membrane with egg cell"
    Please correct me if I am wrong.

    • @hussainbiology

      Sir can you please make a video on cell fate determination of sea urchin.
      Or atleast some notes on the same,here in the comment section.
      I'm very much puzzled with the book's language. Thanking you in appreciation

    • @DD-tr3bf

      And if possible do make a video on arabidopsis embryogenesis & shoot apical meristem. I'm having a tough time trying to learn these topics but these are important for CSIR NET exam.
