Question
Removal of proximal convoluted tubule from the nephron will result in
-
more diluted urine
-
more concentrated urine
-
no change in quality and quantity of urine
-
no urine formation
Solution
A.
more diluted urine
The removal of proximal convoluted tubule from the nephron results in lack of reabsorption of high threshold substance from renal tubules and obligatory reabsorption of water is also affected leading to more diluted urine. Since, proximal convoluted tubule is mainly associated with reabsorption of much water by osmosis, reabsorption of glucose and amino acids by secondary active transport and other salts and ions as Na+, K+, vitamins act by primary active transport.
