Find the incorrect pair.

Options

A. Bowman's capsule - Glomerular filtration
B. PCT- Absorption of `Na^(+)` and `K^(+)`
C. DCT - Absorption of glucose
D. None of these

Answer

To solve the question of finding the incorrect pair, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Identify the First Pair: Bauman's Capsule and Glomerular Filtration**
- Bauman's capsule (also known as Bowman's capsule) is a double-walled cup-like structure that encases the glomerulus in the nephron.
- Its primary function is to participate in the filtration of blood from the glomerular capillaries.
- **Conclusion**: This pair is correctly matched.

2. **Identify the Second Pair: Proximal Convoluted Tubule and Absorption of Sodium and Potassium Ions**
- The proximal convoluted tubule (PCT) is responsible for reabsorbing a significant amount of substances from the filtrate back into the blood.
- It reabsorbs approximately 65% of water, sodium, potassium, and nearly 100% of glucose and amino acids.
- **Conclusion**: This pair is also correctly matched.

3. **Identify the Third Pair: Distal Convoluted Tubule and Absorption of Glucose**
- The distal convoluted tubule (DCT) is involved in the secretion of certain ions and the reabsorption of water and sodium, but it does not absorb glucose.
- Most glucose reabsorption occurs in the proximal convoluted tubule, and the DCT primarily has a secretory function.
- **Conclusion**: This pair is incorrectly matched.

4. **Identify the Fourth Option: None of These**
- This option suggests that none of the pairs are incorrect, which is not true since we have identified an incorrect pair.
- **Conclusion**: This option is also incorrect.

### Final Answer:
The incorrect pair is **Distal Convoluted Tubule and Absorption of Glucose**.
