| 1. | The importance of acrosin in the acrosome reaction has been contested.
|
| 2. | The second process in sperm activation is the acrosome reaction.
|
| 3. | After reaching the zona pellucida the actual acrosome reaction begins.
|
| 4. | Acrosin is the major proteinase present in the acrosome of mature spermatozoa.
|
| 5. | It is stored in the acrosome in its precursor form, proacrosin.
|
| 6. | Upon stimulus, the acrosome releases its contents onto the zona pellucida.
|
| 7. | This test evaluates the acrosome reaction of human spermatozoa.
|
| 8. | Other cells will spontaneously shed their acrosome during the process of apoptosis / necrosis.
|
| 9. | The sperm of " C . elegans " is ameboid, lacking flagella and acrosomes.
|
| 10. | Sperm that are unable to properly go through the acrosome reaction will not be able to fertilize an egg.
