Question

Quizplus · Accepted Answer

Proteases and acrosin are enzymes that are found in sperm. Their function is to break down the protective barriers around the egg, such as the zona pellucida, which allows the sperm to penetrate and fertilize the egg. Without these enzymes, sperm would not be able to successfully fertilize the egg.
