Penting Slow Block Polyspermy

Penting Slow Block Polyspermy- Slow-block to polyspermy is also called cortical reaction. In this reaction, the sperm will be permanently blocked by cortical granules. The release of calcium ion will trigger this reaction.

Slow block to polyspermy The slow block to polyspermy begins within 10 seconds of fusion of the sperm and egg plasma membranes A compound called inositol triphosphate IP3 causes the release of Ca from intracellular stores in the egg endoplasmic reticulum

Slow Block to Polyspermy Cortical Granules The slow block to polyspermy in the sea urchin embryo consists of a physical barrier to further sperm penetration into the egg Cortical granule exocytosis results in the formation of the fertilization envelope often called the fertilization membrane even though the structure is not a true membrane

The fast reaction is known as the fast block to polyspermy which is enabled by an electric charge in the plasma membrane of the egg When the binding of the first sperm is done the membrane potential of the egg changes to the positive side by 20 mV The slow reaction is known as the slow block to polyspermy This is due to the exocytosis of the cortical granules
