Question: Removal of proximal convoluted tubule from the nephron will result in
Options:
A) more diluted urine
B) more concentrated urine
C) no change in quality and quantity of urine
D) no urine formation
Show Answer
Answer:
Correct Answer: A
Solution:
- 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 ammo acids by secondary active transport and other salts and ions as $ N{a^{+}},{K^{+}} $ , vitamins act by primary active transport.
