If liver is removed, which component of blood will increase ?

Options

A. Ammonia
B. Protein
C. Uric acid
D. Urea

Answer

### Step-by-Step Solution:

1. **Understanding the Role of the Liver**: The liver plays a crucial role in the metabolism of nitrogenous waste. One of its primary functions is to convert ammonia, which is highly toxic, into urea through the urea cycle.

2. **Identifying the Components of Blood**: The question asks which component of blood will increase if the liver is removed. The relevant components mentioned are ammonia, protein, uric acid, and urea.

3. **Analyzing the Urea Cycle**: The urea cycle, also known as the ornithine cycle, is responsible for converting ammonia and carbon dioxide into urea. This process occurs in the liver. If the liver is removed, this cycle cannot take place.

4. **Consequences of Liver Removal**: Without the liver, ammonia cannot be converted into urea. As a result, ammonia will accumulate in the bloodstream because it is continuously produced from the metabolism of nitrogen-containing compounds.

5. **Evaluating Each Option**:
- **Ammonia**: Since the liver is responsible for converting ammonia into urea, its removal will lead to an increase in ammonia levels in the blood.
- **Protein**: Proteins are present throughout the body and are not directly affected by liver removal in terms of their concentration in the blood.
- **Uric Acid**: Uric acid levels are not significantly impacted by liver function and are produced from the breakdown of purines.
- **Urea**: Urea cannot be formed without the liver, so its levels will decrease, not increase.

6. **Conclusion**: The component of blood that will increase if the liver is removed is **ammonia**.

### Final Answer:
If the liver is removed, the component of blood that will increase is **ammonia**.
