Question

Glucose is taken back from glomerular filtrate through

• A. Active transport
• B. Passive transport
• C. Osmosis
• D. Diffusion

Answer 1

The correct option is A Active transport

The proximal convoluted tubule is lined by simple cuboidal brush border epithelium which increases the surface area for reabsorption. Nearly all of the essential nutrients and 70-80 percent of electrolytes and water are reabsorbed by this segment. Glucose is completely reabsorbed from PCT by active transport i.e requires energy.

So, the correct answer is 'Active transport'.
