One is found in blood not in nephric filtrate

Options

A. Urea
B. Glucose
C. Amino acids
D. Globulin

Answer

To solve the question "One is found in blood not in nephric filtrate," we need to analyze the components typically found in blood and those that are filtered through the nephron.

### Step-by-Step Solution:

1. **Understanding Nephric Filtrate**:
- Nephric filtrate is the fluid that is formed when blood is filtered through the glomeruli in the kidneys. This process occurs under pressure, allowing certain substances to pass while preventing others.

2. **Components of Blood**:
- Blood contains various substances, including water, ions, small molecules (like glucose and urea), and larger molecules (like proteins).

3. **Filtration Process**:
- During filtration in the kidneys, small molecules and ions can pass through the capillary walls into the Bowman's capsule, forming nephric filtrate. However, larger molecules, particularly proteins, are typically too large to pass through.

4. **Identifying the Options**:
- **Option A: Urea** - Urea is a small molecule and is usually found in nephric filtrate.
- **Option B: Glucose** - Glucose is also a small molecule and can be filtered into nephric filtrate.
- **Option C: Amino Acids** - Amino acids are small enough to pass through and are found in nephric filtrate.
- **Option D: Globulin** - Globulins are large proteins and are typically not found in nephric filtrate due to their size.

5. **Conclusion**:
- Based on the filtration process and the size of the molecules, globulin is the only component listed that is found in blood but not in nephric filtrate. Therefore, the correct answer is **Option D: Globulin**.

### Final Answer:
**Option D: Globulin**
