Unformatted text preview: Describe a hormone and give an example. 6. Describe the G-protein linked receptor system. Mention what binds the receptor and what happens to the receptor, whether the receptor is a kinase, how and when the G protein interacts, what is the role of the G protein and what are some signals used. 7. Compare the tyrosine receptor system to the G protein linked receptor system. 8. Describe an example of the gated ion-channel receptor system? 9. Compare the intracellular receptor system to the other systems and give an example. 10. What occurs in a protein kinase cascade and where does it occur in the signal transduction pathway? 11. Describe the following second messengers and how they act: cyclic AMP, calcium, inositol triphosphate. 12. What is the purpose of the following: (a) signal amplification and (b)scaffolding proteins? 13. Describe how a growth signal goes through the signal transduction pathway....
