Problem:

Question 1: Name three neurotransmitters that activate G-Protein Coupled Receptors. Do you think Lithium affects all of these G-Protein Coupled Receptor Pathways?

Question 2: Diagram the activation of the 5-HT Serotonin Receptor (G-Protein Coupled Receptor) leading to transcriptional activation in a neuron. Include signaling pathways you have learned about in lecture or in your reading that involve G-Protein Coupled Receptors and lead to gene activation. Demonstrate how Lithium may act to disrupt one of these signaling pathways

Include source of information for best answer.
