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 less-than-normal volume of hypoosmotic urine would be produced.
C)A greater-than-normal volume of isoosmotic urine would be produced.
D)A greater-than-normal volume of hyperosmotic urine would be produced.
E)A less-than-normal volume of isoosmotic urine would be produced.

Active transport of sodium is crucial for reabsorption processes in the kidney. If it stops, reabsorption decreases, leading to more water remaining in the tubules, resulting in a greater-than-normal volume of isoosmotic urine.
