Question

Removal of proximal convoluted tubule (PTC) from the nephron will result in:

• A. No change in quality and quantity of urine
• B. No urine formation
• C. More electrolytes and water in urine
• D. Less electrolytes and water in urine

Answer 1

The correct option is C More electrolytes and water in urine

Nearly all the essential nutrients and 70-80 percent of water and electrolytes are reabsorbed by PCT. If PCT is removed, there is no water and electrolytes absorption hence, more electrolytes and water will be present in the urine.
