Answer #1

The cell signaling involves following steps

  1. Synthesis of signalling molecule
  2. Release of signalling molecule
  3. Transport of signalingmolecules to target cell
  4. Binding signaling molecule in receptor
  5. Make changes in the metabolic activities of target cell
  6. Removal of signalling molecule
  7. Removal makes the cellular response

Based on the signal acts the signaling process are calssified as

  1. Endocrine signaling
  2. Pancreatic signaling
  3. Autocrine signaling
  4. JuxtJuxtacrine signaling

So the cell signaling can also occur throug ion channel receptors and receptors with intrinsic enzyme activity ( recptor tyrosine kinase or receptor serine threonine kinase are belong to this particular group).

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)...

You’re studying cellular signaling through G-Protein Coupled Receptors (GPCRs). Specifically you’re working on a pair of newly identified GPCRs, GPCR-A and GPCR-B. Each binds the same small ligand, but activates different heterotrimeric G-proteins that act on adenylate cyclase. Observe and interpret TABLE 1 described below. Assume your experimental Reaction Mixture 1 contain GPCR-A and GPCR-B. You assayed for the levels of cAMP. Your data showed total concentration of cAMP in that reaction mixture was 1000 picomoles per unit protein concentration....
