A man takes large amount of protein. He is likely to excrete more amount of
(a) Urea
(b) Uric acid
(c) Sugar
(d) Salts and water

Options

A. Urea
B. Uric acid
C. Sugar
D. Salts and water

Answer

To solve the question regarding what a man is likely to excrete after taking a large amount of protein, we can follow these steps:

### Step 1: Understand Protein Metabolism
- Proteins are made up of amino acids, which contain nitrogen. When a person consumes a large amount of protein, the body needs to process these amino acids.

### Step 2: Catabolism of Amino Acids
- Excess amino acids are catabolized (broken down) in the body. This process can lead to the release of energy, or the amino acids can be converted into other compounds like glycogen or fat.

### Step 3: Formation of Nitrogenous Waste
- During the catabolism of amino acids, nitrogen is released. This nitrogen must be excreted from the body, as it can be toxic in high amounts.

### Step 4: Identify the Main Nitrogenous Waste Product
- The primary nitrogenous waste product formed from the breakdown of amino acids in humans is urea. Although uric acid is also produced, the majority of nitrogenous waste in humans is excreted as urea.

### Step 5: Conclusion
- Since the question asks what a man is likely to excrete after consuming a large amount of protein, the correct answer is (a) Urea.

### Final Answer:
(a) Urea
