Which is mismatched `,`

Options

A. Bowman's capsule- Glomerular filtration
B. PCT-Absorption of `Na^(+)` and `K^(+)`
C. DCT-Absorption of glucose
D. Collection duct-Absorption of water

Answer

To determine which option is mismatched, let's analyze each option provided in the question based on the functions of different parts of the nephron in the kidney.

### Step-by-step Solution:

1. **Bowman's Capsule - Glomerular Filtration**:
- The Bowman's capsule is indeed responsible for the process of glomerular filtration. It collects the filtrate from the glomerulus, which includes water, ions, and small molecules.
- **Conclusion**: This option is **correct**.

2. **PCT (Proximal Convoluted Tubule) - Absorption of Sodium and Potassium**:
- The PCT is primarily involved in the reabsorption of various substances, including sodium, potassium, water, glucose, and amino acids.
- **Conclusion**: This option is also **correct**.

3. **DCT (Distal Convoluted Tubule) - Absorption of Glucose**:
- The DCT does not absorb glucose. The reabsorption of glucose primarily occurs in the PCT. In the DCT, the focus is on the reabsorption of sodium and the secretion of potassium and hydrogen ions.
- **Conclusion**: This option is **incorrect** and is the **mismatched** statement.

4. **Collecting Duct - Absorption of Water**:
- The collecting duct is responsible for the reabsorption of water, which is regulated by the antidiuretic hormone (ADH).
- **Conclusion**: This option is **correct**.

### Final Answer:
The mismatched option is **DCT - Absorption of Glucose**.
