the events below are what happens when a G-protein coupled receptor is activated. Place the events in the correct order.

-Conformational shift in the alpha subunit of the G protein
-Increase in the affinity of the receptor for a G protein on the cytoplasmic surface of the membrane.
-G protein binds to activated receptor forming a receptor-G protein complex
-Binding of a hormone to a G-protein couple receptor
-Dissociation of the Ga subunit and the GBy complex
-Release of GDP and binding of GTP by the G protein
-Change in conformation of the cytoplasmic loops of the receptor.

When a hormone such as epinephrine binds to a GTP-bound receptor, the G protein alpha subunit...
When a hormone such as epinephrine binds to a GTP-bound receptor, the G protein alpha subunit leaves to activate adenylyl Cyclase. When the alpha subunit re-associates with the beta/gamma subunits of the G protein, is the hormone still attached to the GTP-bound receptor? When exactly does the hormone leave the receptor — is it when the G protein is GTP-activated or when the G protein is reassembled back into alpha/beta/gamma?

Acetylcholine binds to a G-coupled protein receptor on the heart muscle to make the heart beat more slowly. It does so by stimulating the opening of K+ channels in the plasma membrane, which makes it more difficult to initiate and action potential. Describe the following on contraction of the heart. A.) Addition of a drug that inhibits the GTPase activity of the Ga subunit. B.) Mutations in the K+ channel that keep it closed all the tiem. C.) A mutation...

Which of the following statements about G-Protein Coupled Receptor (GPCR) signaling or Protein Kinase A (PKA) activation is correct? I. GPCR kinases phosphorylate GPCRs on their intracellular surface promoting the binding ofβ-Arrestin and the inhibition of GPCR signaling. II. The pseudosubstrate sequence located in the PKA regulatory domain binds to an AKAP protein in the absence of cAMP. III. The PKA catalytic and regulatory domains are part of a single polypeptide chain. IV. The slow hydrolase activity of the PKA...

Where is the G-protein complex when a ligand is not bound to its receptor? The beta and gamma subunits are attached to the inner surface of the receptor. The three subunits are together but not attached to the inner surface of the receptor. The alpha subunit is attached to the inner surface of the receptor. Which of the following does NOT affect the rate of diffusion through a membrane? membrane pore size solute size solute concentration solute kinetic energy The...

How does G⍺ stay associated with the plasma membrane after release from GPCR? Lipid rafts. G⍺ is phosphorylated. G⍺ is farnesylated. G⍺ is palmitoylated. G⍺ is covalent bound to positive charge of phospholipids. G⍺ contains a transmembrane domain that is enriched for hydrophobic residues. Why is it important that G⍺ stay associated with the plasma membrane after release from GPCR? It isn’t, in fact this is one way to prevent “runaway signaling” (i.e. how G⍺ acts as a molecular timer)...
