Question

Quizplus · Accepted Answer

Hyaluronidase and acrosin are the two proteolytic enzymes responsible for digesting a path through the zona pellucida during fertilization. Hyaluronidase helps to break down the hyaluronic acid present in the zona pellucida, while acrosin helps to break down the glycoproteins present in the zona pellucida.
