In a comparison of amounts of urea in human urine, the largest amount of urea would be found with a diet very rich in `:-`

Options

A. Animal fat
B. Simple carbohydrates (sucrose)
C. Complex carbohydrates (starches0
D. Protein

Answer

To determine the largest amount of urea found in human urine based on diet, we need to analyze the relationship between dietary components and urea production.

### Step-by-Step Solution:

1. **Understanding Urea Formation**: Urea is a nitrogenous waste product formed from the breakdown of proteins in the body. When proteins are consumed, they are digested into amino acids.

2. **Role of Amino Acids**: Amino acids contain an amino group (NH2). When proteins are metabolized, the amino group is removed in a process called deamination.

3. **Deamination Process**: During deamination, the amino group is converted into ammonia (NH3), which is then transported to the liver.

4. **Urea Cycle**: In the liver, ammonia is converted into urea through the urea cycle. This process helps in detoxifying ammonia, which is toxic at high levels.

5. **Dietary Influence on Urea Production**: A diet that is rich in proteins will lead to a higher intake of amino acids. Consequently, more amino acids will undergo deamination, resulting in increased production of ammonia, which is then converted into urea.

6. **Conclusion**: Therefore, a diet very rich in proteins will result in the largest amount of urea being excreted in human urine.

### Final Answer:
The largest amount of urea would be found with a diet very rich in **proteins**.
