← Human Body & HealthIf fertilization of a human egg occurs, which consequence dominates due to the acrosomal reaction?
A)Blocking polyspermy through cortical granules
B)Releasing enzymes to bind receptors
C)Increasing sperm motility via capacitation
D)Penetration of the zona pellucida✓
💡 Explanation
The acrosomal reaction releases enzymes that digest the zona pellucida, allowing sperm penetration because the sperm must breach this layer for fertilization. Therefore, penetration dominates, rather than simply binding or initiating later blocks to polyspermy.
