Essential nutrients like glucose, amino acids and vitamins reabsorbed in

Options

A. DCT
B. PCT
C. Loop of Henle
D. Collecting duct

Answer

To answer the question about where essential nutrients like glucose, amino acids, and vitamins are reabsorbed, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks where essential nutrients such as glucose, amino acids, and vitamins are reabsorbed in the nephron of the kidney.

2. **Identifying the Nephron Parts**: The nephron consists of several parts including the renal corpuscle, proximal convoluted tubule (PCT), loop of Henle, distal convoluted tubule (DCT), and collecting duct. Each part has specific functions.

3. **Function of the Proximal Convoluted Tubule (PCT)**: The PCT is the first segment of the renal tubule that receives the filtrate from the renal corpuscle. It is primarily responsible for the reabsorption of essential nutrients.

4. **Nutrient Reabsorption in the PCT**: In the PCT, a significant amount of glucose, amino acids, and vitamins are reabsorbed back into the bloodstream. This is crucial for maintaining the body's nutrient levels.

5. **Other Parts of the Nephron**:
- The Loop of Henle primarily concentrates urine and does not play a significant role in nutrient reabsorption.
- The Distal Convoluted Tubule (DCT) and Collecting Duct are involved in the reabsorption of water and ions but are not the primary sites for glucose and amino acids.

6. **Conclusion**: Based on the functions of the nephron parts, the correct answer to the question is that essential nutrients like glucose, amino acids, and vitamins are reabsorbed in the Proximal Convoluted Tubule (PCT).

### Final Answer:
Essential nutrients like glucose, amino acids, and vitamins are reabsorbed in the **Proximal Convoluted Tubule (PCT)**.
