1. The part of the sperm containing proteolytic enzymes to digest the zona pellucida is the: A. capacitor B. head C. corona D. acrosome E. cumulus D. is correct. The acrosome is the part of the sperm containing proteolytic enzymes to digest the zona pellucida. It is exposed by the process of capacitation. Then, under the influence of substances released by corona radiata cells, it releases its proteolytic enzymes and penetrates the oocyte. 2. The ovulated mammalian oocyte is arre...
