Question

Reabsorption of useful substances from glomerular filtrate occurs in

• A. Collecting tube
• B. Loop of Henle
• C. Proximal convoluted tubule
• D. Distal convoluted tubule

Answer 1

The correct option is C Proximal convoluted tubule

PCT is lined by simple cuboidal brush border epithelium which increases the surface area for reabsorption. Nearly all of the essential nutrients (glucose, small proteins) and 70-80 % of electrolytes (NaCl, K+ ) and water are reabsorbed by this segment. Hence, reabsorption of useful substances from glomerular filtrate occurs in the proximal convoluted tubule.

So, the correct answer is 'Proximal convoluted tubule'.
