Question

Select the incorrect match w.r.t. materials reabsorbed in different parts of the nephron of kidney.

• A.

  Parts of nephron	Reabsorbed
  Ascending limb of loop of Henle	NaCl

• B.

  Parts of nephron	Reabsorbed
  Descending limb of loop of Henle	Water and NaCl

• C.

  Parts of nephron	Reabsorbed
  PCT	Glucose, amino acids, vitamin C

• D.

  Parts of nephron	Reabsorbed
  DCT	NaCl, $HC{O}_3^{-}$

Answer 1

The correct option is B

Parts of nephron	Reabsorbed
Descending limb of loop of Henle	Water and NaCl

Ascending limb of loop of Henle is permeable for salts and ions (NaCl, K+). Descending limb of loop of Henle is permeable for water. Hence, water is reabsorbed in descending limb of loop of Henle, not NaCl.

Glucose, amino acids, proteins, vitamins are reabsorbed by PCT (proximal convoluted tubule).
$HC{O}_3^{-},NaCl,H_{2}O$ is reabsorbed by DCT (distal convoluted tubule).
