| 1. | It is created by the products secreted by the cortical granules.
|
| 2. | Mammalian cortical granules have been shown to contain high levels of carbohydrates.
|
| 3. | Cortical granule exocytosis has been shown to occur directly following a calcium wave.
|
| 4. | Evidence has indicated the presence of the protein, calreticulin, within the cortical granule.
|
| 5. | Once the egg is fertilized, then the cortical granules exocytose their contents into the extracellular matrix.
|
| 6. | The oocyte has cortical granules peripherally located under the cortex that contain a proteolytic protein called metalloendoproteases.
|
| 7. | As demonstrated in unfertilized vertebrate oocytes, cortical granule exocytosis is induced when calcium is artificially increased.
|
| 8. | "' Hyalin "'is a protein released from the cortical granules of a egg.
|
| 9. | An assortment of hypotheses exist concerning the biological function of CGFDs and pre-fertilization cortical granule exocytosis.
|
| 10. | The proteinases present in mammalian cortical granules primarily serve to modify the zona pelucida during the zona reaction.
