It detects pituitary hormones in urine that correlate with the ovulatory cycle. The corpus luteum, located in the ovary. You are studying ZP3 in the laboratory of its discoverer, Paul Wassarman. You and others have used a variety of techniques to study ZP3's function. Match the statements about ZP3 on the left with the appropriate response from the right-hand column that could be used to obtain that information.
Successful fertilization requires that sperm interact with the egg or oocyte in specific ways.
Acrosome reacted sperm can interact with egg normally Sea urchin sperm exposed to egg jelly Sea urchin egg from same species pretreated with purified bindin no Bindin pretreatment will mean bindin receptors are already occupied, hence sperm will not bind, even though it has been acrosome reacted. The clamp mimics the fast block, so binding of sperm will be poor. Match the following events with the major protein system that it requires. By altering the properties of some eggs or oocytes, it is possible to study the role of signal transduction in the blocks to polyspermy and egg activation. Please answer the following questions regarding these ionic events.
