How does ADH function at the cellular level?
A)ADH stimulates the reabsorption of glucose through channel proteins.
B)It triggers the synthesis of an enzyme that makes the phospholipid bilayer more permeable to water.
C)It causes membranes to include more phospholipids that have unsaturated fatty acids.
D)It causes an increase in the number of aquaporin molecules of collecting duct cells.
E)It decreases the speed at which filtrate flow through the nephron leading to increased reabsorption of water.

Question

Quizplus · Accepted Answer

ADH causes an increase in the number of aquaporin molecules in the collecting duct cells. Aquaporins are channel proteins that allow for the passive transport of water across the cell membrane. With more aquaporins, more water can be reabsorbed from the urine back into the bloodstream. This helps to conserve water and prevent dehydration.
