Question

Imagine a situation in which the number of urea leak channels increased dramatically in the ascending limb of the loop of Henle. What could be one likely consequence of this situation?

Answer 1

The correct answer for the question that is being presented above is this one: "B. Aldosterone-regulated Na+ pump activity would increase dramatically to stabilize the osmotic concentration gradient."

Here are the following choices:
A. The final urine output would increase greatly because of the increase in ADH-regulated water reabsorption.
B. Aldosterone-regulated Na+ pump activity would increase dramatically to stabilize the osmotic concentration gradient.
C. The increased solute concentration in the vasa recta would stimulate additional water reabsorption.
D. The concentration gradient of the renal medulla would remain unaffected.
