Fertilization is the union of an ovum and a spermatozoon. When a sperm contacts the surface of an egg, it initiates metabolic reactions within the egg that trigger the onset of embryonic development. The acrosome releases enzymes to digest the zona pellucida. The plasma membranes of the two gametes fuse, allowing the whole sperm to enter the egg. The egg releases enzymes from cortical granules to. Plasma vectors

Hormones bind to receptors on the plasma membrane. The hormone itself is the first messenger. Binding to the receptors activates a second messenger inside the cell. The second messenger causes intracellular effects. Plasma vectors
