Receptor tyrosine kinase that activates the MAP Kinase signalling cascade This pathway inherent to growth factors, not ADH. G-protein coupled receptor pathway that activates downstream protein kinase C This receptor-pathway corresponds to that of AVPR1. G-protein coupled receptor pathway that inhibits the cAMP signalling pathway The Gi-protein coupled receptor pathway inactivates adenylyl cyclase. On the contrary, ADH activates adenylyl cyclase by acting on the Gs-coupled AVPR2 receptors. G-protein coupled receptor pathway that activates the phosphatidylinositol signalling pathway This receptor-pathway corresponds to that of AVPR1. The phosphatidylinositol pathway activates downstream protein kinase C. Physiology A researcher is studying the intracellular signaling pathways of anti-diuretic hormone (ADH) prior to its terminal hormonal effects. He observes that ADH molecules have several different binding sites in renal tissues. Which of the following intracellular signaling pathways is utilized by ADH V2 receptors to increase water reabsorption in the collecting ducts? A Renal 2020-10-28T00:35:30Z 2459150.5246528 WBR0444
