Glucose and amino acids are reabsorbed in

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Nephron Structure:**
- The nephron is the functional unit of the kidney, consisting of various parts including the glomerulus, proximal convoluted tubule (PCT), distal convoluted tubule (DCT), and collecting duct.

2. **Identifying the Function of Each Part:**
- The PCT is primarily responsible for the reabsorption of essential substances from the filtrate.
- The DCT and collecting duct also play roles in reabsorption, but to a lesser extent for glucose and amino acids.

3. **Focusing on Glucose and Amino Acids:**
- Glucose and amino acids are vital nutrients that the body needs to retain.
- The PCT reabsorbs nearly 100% of the glucose and amino acids present in the filtrate.

4. **Conclusion:**
- Since glucose and amino acids are reabsorbed primarily in the proximal convoluted tubule, the correct answer to the question is the PCT.

5. **Final Answer:**
- Glucose and amino acids are reabsorbed in the **proximal convoluted tubule (PCT)**.
