In which part of nephron, reabsorption of glucose is maximum from filtrate?

Options

A. Henle's loop
B. PCT
C. DCT
D. Collecting tubule

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Nephron Structure**: The nephron is the functional unit of the kidney and consists of two main parts: the glomerulus and the renal tubule. The renal tubule is further divided into several segments, including the proximal convoluted tubule (PCT), loop of Henle, distal convoluted tubule (DCT), and collecting duct.

2. **Identifying the Function of Each Part**: The glomerulus is responsible for the filtration of blood, while the renal tubule is responsible for the reabsorption and secretion of various substances.

3. **Focusing on the Proximal Convoluted Tubule (PCT)**: The PCT is the first segment of the renal tubule that follows the glomerulus. It plays a crucial role in reabsorption.

4. **Reabsorption in the PCT**: The PCT is where the maximum reabsorption of glucose occurs. Approximately 70-80% of electrolytes and water are reabsorbed in this segment. Additionally, glucose and amino acids are almost completely reabsorbed here due to the presence of specialized epithelial cells with a brush border that increases the surface area for absorption.

5. **Conclusion**: Based on the functions and characteristics of the nephron, the part of the nephron where the maximum reabsorption of glucose occurs is the Proximal Convoluted Tubule (PCT).

**Final Answer**: The maximum reabsorption of glucose from filtrate occurs in the Proximal Convoluted Tubule (PCT).
