Proper functioning of the human kidney requires considerable active transport of sodium in the kidney tubules.If these active transport mechanisms were to stop completely,how would urine production be affected?
A)No urine would be produced.
B)A lower-than-normal volume of urine which was less concentrated than the blood (hypotonic)would be produced.
C)A lower-than-normal volume of urine which was more concentrated than the blood (hypertonic)would be produced.
D)A greater-than-normal volume of urine equal in concentration to the blood (isotonic)would be produceD.
E)A greater-than-normal volume of urine that was more concentrated than the blood (hypertonic)would be produced.

Active transport of sodium in the kidney tubules is crucial for reabsorbing water and concentrating urine. Without it, water cannot be reabsorbed effectively, leading to the production of a greater volume of urine that is isotonic with the blood, as there would be no gradient to facilitate water reabsorption.
