Which of the following is NOT a function of the vertebrate liver?

Options

A. Converts excess glucose to glycogen
B. Deaminates excess amino acids
C. Produces bile
D. Conserves body water

Answer

To determine which of the following is NOT a function of the vertebrate liver, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Liver Functions**: The liver has several important functions including metabolism, detoxification, and production of biochemicals necessary for digestion.

2. **Option Analysis**:
- **Option 1: Convert excess glucose to glycogen**: This is a function of the liver. The liver converts excess glucose into glycogen for storage.
- **Option 2: Deaminates excess amino acids**: This is also a function of the liver. The liver deaminates amino acids, which is the process of removing the amino group from amino acids, allowing the body to use them for energy or convert them into other compounds.
- **Option 3: Produce bile**: This is another function of the liver. The liver produces bile, which is important for digestion and absorption of fats.
- **Option 4: Conserves body water**: This is NOT a function of the liver. The liver does not play a direct role in conserving body water; this function is primarily associated with the kidneys.

3. **Conclusion**: Based on the analysis, the correct answer is **Option 4: Conserves body water**, as it is not a function of the vertebrate liver.

### Final Answer:
The function that is NOT performed by the vertebrate liver is **Option 4: Conserves body water**.
