The complete reabsorption of glucose takes place in `:`

Options

A. Collecting tubule
B. Distal tubule
C. Proximal covoluted tubule
D. Henle loop

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where the complete reabsorption of glucose occurs in the nephron of the kidney.

2. **Identify the Parts of the Nephron**: The nephron consists of several parts including the Proximal Convoluted Tubule (PCT), Loop of Henle, Distal Convoluted Tubule (DCT), and Collecting Duct.

3. **Function of the Proximal Convoluted Tubule (PCT)**: The PCT is primarily responsible for the reabsorption of various substances, including glucose, amino acids, and electrolytes. It reabsorbs about 70-80% of the filtrate.

4. **Role of Other Parts**:
- **Loop of Henle**: Primarily involved in the reabsorption of water and electrolytes, but not glucose.
- **Distal Convoluted Tubule (DCT)**: Involved in the reabsorption of water and electrolytes, but does not reabsorb glucose.
- **Collecting Duct**: Primarily involved in the reabsorption of water and some electrolytes, but again, no glucose reabsorption occurs here.

5. **Conclusion**: Since the PCT is the only part of the nephron where glucose is completely reabsorbed, the answer to the question is the Proximal Convoluted Tubule (PCT).

**Final Answer**: The complete reabsorption of glucose takes place in the Proximal Convoluted Tubule (PCT).
