Question
Which of the following organelles located between the plasma membrane and the nucleus of the sperm head, contains digestive enzymes for penetration of the egg's protective coat?Multiple choice question.RibosomeAcrosomePhagosomePeroxisome
Solution
The correct answer is Acrosome. The acrosome is an organelle that develops over the anterior half of the head in the spermatozoa (sperm cells) of many animals. It is a cap-like structure derived from the Golgi apparatus. The acrosome contains digestive enzymes (including hyaluronidase and acrosin). These enzymes break down the outer membrane of the egg, known as the zona pellucida, allowing the sperm to penetrate and fertilize the egg.
