Question

Identify the incorrect statement regarding the acids excreted by the human kidney.

विकल्प

• the pH of urine is normally lesser than plasma.

• The intercalated DCT releases hydrogen ions to reabsorb bicarbonate from tubular fluid.

• Filtered bicarbonates are absorbed by cation transport.

• All the bicarbonate is normally reabsorbed in the first half of the distal tubule.

Answer 1

All the bicarbonate is normally reabsorbed in the first half of the distal tubule.

Explanation:

The assertion Because most bicarbonate ion reabsorption occurs in the proximal convoluted tubule of the nephron and only a small portion is reabsorbed by the distal convoluted tubule and loop of Henle, the assumption that all bicarbonate is normally reabsorbed in the first half of the distal tubule is incorrect and can be corrected.
