6.What are second messengers, and what role do they play in hormonal control of cell function?

6- Investigate and explain the difference between a neurotransmitter and a neuromodulator

1. If a mutation were to occur to disrupt the localization of ankyring, such that this protein became distributed throughout the Purkinje cell body and axon, what phenotype would you expect? Briefly explain your reasoning, assuming that the mutation does not disrupt interactions between ankyring and neurofascin.

17. Explain the concepts of specificity, competition, and saturation as they relate to membrane receptors.  Explain how membrane receptors show specificity, competition, saturation. Some key concepts which relate to this question are first messengers, binding sites, and ligands.
