Vedclass · Answer

(C) The $Zona$ $pellucida$ is a glycoprotein layer surrounding the plasma membrane of a mammalian oocyte. It plays a crucial role in fertilization by acting as a species-specific barrier for sperm binding. Once a single sperm penetrates the $Zona$ $pellucida$ and fuses with the egg membrane,cortical granules release enzymes that modify the $Zona$ $pellucida$ (the zona reaction),which prevents other sperm from binding or penetrating,thereby preventing polyspermy. It also protects the developing embryo during its transport through the oviduct and prevents premature implantation.
