[solved]-Consider The Following In Vitro Fertilization Experiment Using Sea Urchin S Purpuratus Gametes Sperm And Eggs First Sperm Were Induced To Acrosome React With Isolated Fucose Sulfate Polysacc 73326

Consider the following in vitro fertilizationexperiment using sea urchin (S. purpuratus) gametes (spermand eggs): First, sperm were induced to acrosome react withisolated fucose sulfate polysaccharide (FSP)-the acrosome inducingsubstance from the jelly layer-, followed by brief incubation ofthe acrosome reacted sperm with isolated/purified “BINDIN receptors(ERB1).” These sperm were then washed briefly to remove anyunbound receptors and were then used to fertilize de-jellied eggs(eggs from which the jelly layer has been removed). Result:very few or no eggs were fertilized, no matter how much sperm wereadded. Explain this result (6 pts.)Jelly layer was removed is NOT the answer because we usedpre-acrosome reacted sperm.
