- Calcium ions (a) can act as second messengers (b) split calmodulin (c) are kept at higher concentration in the cytosol than in the extracellular fluid (d) are produced in the ER by protein kinases and protein phosphatases (e) typically terminate signaling cascadesHistamine binds to the H1 G-protein-linked receptor to initiate the itchiness and airway constriction associated with an allergic response. If a mutation in the associated G-protein’s alpha subunit prevented the hydrolysis of GTP how would the allergic response change? More severe allergic response compared to normal G-protein signaling. Less severe allergic response compared to normal G-protein signaling. No allergic response. No change compared to normal G-protein signaling.3 of 16 Which statement about the IP3 DAG pathway is false? O Diacylglycerol can act as a second messenger. Inositol trisphosphate can act as a second messenger. O Protein kinase C can phosphorylate a wide variety of proteins. O Inositol trisphosphate remains bound to the membrane after phospholipase C catalyzes its formation. Inositol trisphosphate can open ion channels in the membraņes of smooth endoplasmic reticulum, releasing calcium into the cytoplasm.
- 2. Following Figure shows that intracellular signaling pathways can be highly interconnected? signal molecule plasma membrane activated GPCR activated RTK G protein G protein → phospholipase C PI 3-kinase Ras-GEF phosphorylated inositol phospholipid adenylyl cyclase IP3 diacylglycerol Ras Ca+ MAP kinase kinase kinase cyclic AMP protein kinase 1 calmodulin MAP kinase kinase PKA CaM-kinase РКС MAP kinase Akt kinase ALTERED CELL BEHAVIOR ECB4 EQ16.51/Q16.61 From the information in above Figure, which of the following statements is incorrect, and explain your opinion(explanation)? A. The GPCR and the RTK both activate phospholipase C. B. Activation of either the GPCR or the RTK will lead to activation of transcriptional regulators. C. CaM-kinase is only activated when the GPCR is active and not when the RTK is active. D. Ras is activated only when the RTK is active and not when the GPCR is active.Cytokine receptors and tyrosine kinase receptors are similar in all of the following ways EXCEPT one. Which one is the exception? O They are both down-regulated by lysosomal degradation They both involve receptor exoplasmic domain dimerization They both result in an effector protein entering the nucleus O They both involve cytosolic domain phosphorylationWhich of the following statements is true Ras becomes activated when it exchanges its GDP for GTP AKT phosphorylation results in an inactive Bcl2 MAP kinase is important for phosphorylating MAP kinase kinase PI-3 kinase phosphorylates an inositol phospholipid in the cytoplasm

Based on these diagrams, which of the following statements are likely true? Choose only the best answer. Cell 1 Receptor 1 ✓ Adenylyl cyclase V CAMP V Protein kinase A ✓ Protein kinase V Response 1 Receptor 2 ✓ Protein kinase V Protein kinase V Response 2 Cell 2 Only Cell 1 contains a relay molecule.
