question 10 of 13
the presence of a high concentration of aquaporins (water channels) in the membranes of certain kidney tubule cells is crucial for their specialized role in
efficient water reabsorption back into the bloodstream
the active transport of glucose out of the urine
the synthesis of hormones that regulate blood pressure

Explanation:

Aquaporins are water - channel proteins. In kidney tubule cells, they facilitate the reabsorption of water from the filtrate back into the bloodstream. Glucose transport is not related to aquaporins, and aquaporins are not involved in hormone synthesis for blood - pressure regulation.

Answer:

Efficient water reabsorption back into the bloodstream
