Consider the case of a rare mutant in which the concentration of solutes in the kidney medulla interstitial spaces is equal to the concentration of solutes in the liquid in thelumen of the medullary collecting duct in the kidney. The defective moleculesassociated with this rare mutation areNOT located in the epithelial cells of the kidneymedullary collecting duct; the defective molecules are located in other cells of thekidney. In this rare mutant, an increase in the amount of vasopressin that binds toV2Receptors in the kidney will lead to an increase in the amount ofA.cAMP inthe cytosol of epithelial cells in the kidney medullary collecting duct.B.AQP2 molecules in the luminal membranes of epithelial cells in the kidneymedullary collecting duct.C.water that is reabsorbed into the blood plasma from the lumen of the collectingduct.D.A and B.E.A and C.F.B and C.G.A, B, and C.H.None of the above
