Question
The excretory product that has the highest toxicity is
- urea
- uric acid
- ammonia
- all are equally toxic
Solution
The excretory product that has the highest toxicity is ammonia.
Here's why:
-
Urea, uric acid, and ammonia are all waste products produced by organisms as a result of protein metabolism.
-
Ammonia is the most toxic of the three. It is a byproduct of protein catabolism and is highly toxic due to its high pH.
-
Urea is less toxic than ammonia. It is produced in the liver from ammonia through a process called the urea cycle.
-
Uric acid is the least toxic of the three. It is a product of nucleic acid metabolism and is excreted by birds and reptiles.
-
Therefore, of the three options given, ammonia is the most toxic.
