Aquaporins are membrane channels that are highly specific to the movement of water.If aquaporins are inserted into the membranes of a cell that does not normally contain them, A) the flow of Na⁺ through aquaporins will increase. B) the intracellular concentration of K⁺ will increase. C) carrier proteins will bind water and leave the cell. D) the membranes will become more permeable to water. E) the electrical properties of the cells will be altered.

Question

Quizplus · Accepted Answer

Aquaporins facilitate the movement of water across the membrane and if inserted into a membrane of a cell that does not normally contain them, it will increase the membrane's permeability to water. Therefore, the correct answer is D. Choice A, B, C, and E are incorrect because they do not accurately describe the function of aquaporins.
