Reabsorption of useful substances from glomerular filtrate occurs in

Options

A. collecting tube
B. loop of Henle
C. proximal convoluted tubule
D. distal convoluted tubule

Answer

C

Explanation

Proximal convoluted tubule is the main site for the reabsorption of useful substances from glomerular filrtate. In PCT complete reabsorption by active transport takes place for glucose. PCT reabsorbs most of the amino acids and vitamin-C about 70% of `Na^(+)` and nearly 75% of `K^(+)` and a large amount of `Ca^(2+)` from glomerular filtrate. `Cl^(-)` is reabsorbed by diffusion. 70% of water from filtrate is also reabsorbed in PCT by osmosis.
