Which of the following enhances obligatory water reabsorption?
A)presence of aldosterone in the distal tubule
B)ATP
C)presence of high levels of glucose in the filtrate
D)aquaporins

Question

Quizplus · Accepted Answer

Aquaporins are water channels present in the membrane of renal tubules that enhance water reabsorption. They facilitate the movement of water from the tubular lumen to the interstitial space and are crucial for the production of concentrated urine. Choice A is incorrect because aldosterone enhances sodium reabsorption in the distal tubule, not water reabsorption. Choice B is incorrect because ATP is not directly involved in water reabsorption. Choice C is incorrect because the presence of high levels of glucose in the filtrate can actually impair water reabsorption by creating an osmotic force that draws water into the tubules.
