A sperm encounters an egg's jelly coat thus triggering the acrosomal reaction. What is the first step of this reaction (i.e., what happens next)? The acrosome binds to the receptor on the ovum allowing the head to enter the ovum. The midpiece releases enzymes that cause the acrosome, along with the head, to separate from the flagellum and enter the egg. The acrosome releases enzymes that break down the jelly coat. The ovum releases calcium which then capacitates the acrosome.
