Explanation:

Aquaporins are water - channel proteins. In kidney tubule cells, they facilitate the movement of water. The main function related to their high concentration in kidney tubule cell membranes is to enable efficient water reabsorption back into the bloodstream, which helps in maintaining the body's water balance. Glucose transport is done by glucose transporters, not aquaporins, and hormone synthesis is not related to aquaporin function.

Answer:

Efficient water reabsorption back into the bloodstream.
