A)It regulates water turnover in the mammalian kidney.
B)ADH secretion is stimulated by high blood osmolarity.
C)It ultimately acts to reabsorb more water.
D)It exerts it effects via the cAMP pathway.
E)It does not involve the use of aquaporin molecules.

Question

Quizplus · Accepted Answer

Antidiuretic hormone (ADH) functions by increasing the permeability of the kidney's collecting ducts to water, primarily through the insertion of aquaporin-2 channels into the cell membranes of the duct's cells, facilitating water reabsorption. Therefore, stating that it does not involve the use of aquaporin molecules is incorrect.
