How would the following experimental procedures affect signaling in the systems described?
a) When sperm are added to eggs, they bind and result in the generation of DAG and the release of intracellular calcium in the egg. This signaling event in turn activates the egg and it divides. If you inject an antibody to the IP3 receptor that inhibits the binding of IP3 to its receptor, and then add sperm to these eggs, what would you expect the experimental result to be and why?
