During sperm penetration, human eggs are still surrounded by follicular cells.
Therefore, the correct answer is Option D.
<h3>What changes does egg undergo for fertilization?</h3>
- An egg goes through a few changes at the hour of sperm penetration during fertilization.
- These progressions happen at the cell surface, in development, physiology and gene expression.
- For fertilization, a sperm should combine with the cell membrane and afterward infiltrate the egg cells.
- Infiltration through the egg cell or extracellular matrix (ECM) is a troublesome task.
- The acrosome of the egg goes through acrosomal reaction to get through the hard shell of cell.
- To go through the follicle cells encompassing the egg or oocyte, the sperm discharges hyaluronidase enzyme.
- This chemical isn't delivered until the sperm comes into contact with the egg cell's zona pellucida.
