Most of the glucose that is filtered through the glomerulus undergoes reabsorption in

Options

A. distal tubule
B. collecting duct
C. proximal tubule
D. ascending limb of the loop of Henle

Answer

**Step-by-Step Solution:**

1. **Understanding the Nephron Structure**: The nephron is the functional unit of the kidney and consists of several parts including the Bowman's capsule, glomerulus, proximal tubule, loop of Henle, distal tubule, and collecting duct.

2. **Role of the Glomerulus**: The glomerulus is a network of capillaries located within the Bowman's capsule. It is responsible for the process of ultrafiltration, where blood is filtered to form a filtrate that contains water, ions, glucose, and other small molecules.

3. **Reabsorption in the Nephron**: After ultrafiltration, the filtrate passes through different parts of the nephron. The reabsorption process is crucial as it allows the body to reclaim essential substances from the filtrate.

4. **Identifying the Site of Glucose Reabsorption**: Among the various parts of the nephron, the proximal convoluted tubule (PCT) is primarily responsible for the reabsorption of glucose. Approximately 90-100% of the glucose filtered through the glomerulus is reabsorbed here.

5. **Conclusion**: Therefore, the correct answer to the question is that most of the glucose filtered through the glomerulus undergoes reabsorption in the proximal tubule.

**Final Answer**: Most of the glucose that is filtered through the glomerulus undergoes reabsorption in the **proximal tubule**.
