In the "outside-in" pathway leading from GPCR activation to gene activation, which of the following enzymes enters the nucleus to help initiate gene transcription? Protein Kinase Phospholipase C Adenylyl cyclase Phosphatase Ethanol, steroids, and general anesthetics all (choose the best answer) Do not affect GABA(A) receptors Are inverse GABA(A) agonists Allosterically potentiate GABA(A) receptors Competitively inhibit GABA binding to GABA(A) receptors

QUESTION 3 Signal transduction is commonly mediated through a series of kinases. What do these enzymes do? generate ATP, activate phosphates, phosphorylate target proteins, and activate receptors. QUESTION 4 Epinephrine is given to people with anaphylactic allergic reactions. This hormone is also normally secreted by the adr QUESTION 5 Adenylyl cyclase is involved in many signal transduction pathways. What does it do? Hydrolyzes ATP to ADP.
