Question

In the kidney, glucose is mainly absorbed in……….

• A. Loop of Henle
• B. Bowman's capsule
• C. Distal convoluted tubule
• D. Proximal convoluted tubule

Answer 1

The correct option is D

Proximal convoluted tubule

The correct option is D.

Explanation of the correct option:

1. Glucose is absorbed in the proximal convoluted tubule (PCT) which is one of the tubules present in Nephron.
2. Their epithelial cells consist of luminal brush border cells.
3. They are densely covered with microvilli and hence they increase the absorptions.
4. They also help in the regulation of the pH of the filtrate by the exchange of ions.

Explanation of the incorrect option:

Option A:

1. The loop of Henle is present in between the proximal convoluted tubule and the distal convoluted tubule.
2. It helps in the transport of ions.
3. It also helps in the conservation of water by concentrating the urine.

Option B:

1. Bowman’s capsule is a sac-like organ that is present in the nephron, enclosing the glomerulus in it.
2. Their main function is the filtration of the filtrate passing through the nephron.

Option C:

1. It is one of the parts of tubules present in the nephron.
2. It helps in regulating the pH of body fluids.

Final answer: In the kidney, glucose is mainly absorbed in the Proximal convoluted tubule.
