In public urinals, the urine on standing givesa pungent smell, due to ...
Explanation:
The pungent smell in public urinals is caused by the conversion of urea into ammonia by bacteria. Here is a detailed explanation:
Conversion of urea into ammonia:
- Urea is a waste product produced by the liver as a result of protein metabolism.
- When urine comes into contact with bacteria in public urinals, the bacteria enzymatically break down urea into ammonia.
- This conversion is facilitated by the enzyme urease, which is produced by certain bacteria.
- Ammonia has a strong and pungent odor, which is responsible for the unpleasant smell in public urinals.
Other options:
- Option A: The ornithine cycle is a metabolic pathway involved in the conversion of ammonia into urea in the liver. It is not directly related to the pungent smell in urinals.
- Option B: While both urea and uric acid can be converted into ammonia, in the context of public urinals, it is primarily urea that is converted.
- Option D: None of the other options accurately explain the cause of the pungent smell in public urinals.
In conclusion, the pungent smell in public urinals is due to the conversion of urea into ammonia by bacteria.
