Question

In man, in which part of the uriniferous tubule reabsorption of glucose occurs?

• A. Collecting tube
• B. Henle's loop
• C. Distal convoluted tubule
• D. Proximal convoluted tubule

Answer 1

Answer: (D)

Proximal convoluted tubule

• In man, reabsorption of glucose occurs in proximal convoluted tubule by the active transport. The cubical cells of proximal tubules have microvilli and mitochondria to increase the surface area for absorption and active transport. It is the part of the proximal tubule.
• All essential nutrients and 70-80 percent of electrolytes, glucose and water are absorbed in this part. It is also involved in the selective secretion of hydrogen ions, ammonia and potassium ions into the filtrate and maintaining the pH and ionic balance of the body.

So, the correct answer is option D.
