3 forms of nitrogenous waste produced by different types of vertebrates
Answers
Answer:
Nitrogenous waste takes three forms:
- ammonia - the direct waste produced as a byproduct of protein metabolism. Produced by all animals. ...
- urea - formed in the liver from the conversion of ammonia. ...
- uric acid - in reptiles and birds uric acid is formed in the liver from the conversion of ammonia.
Answer: The three major nitrogenous wastes are :
1.Urea :- Urea (also known as carbamide) is a waste product of many living organisms, and is the major organic component of human urine. This is because it is at the end of chain of reactions which break down the amino acids that make up proteins.
2.Ammonia :- Ammonia is the highly nitrogenous waste of all animals but most of them convert it into its less toxic forms such as urea or uric acid . Only animals who have constant access to water , can excrete waste in the form of ammonia such as some amphibians and fishes because it requires large amount of water for dilution and flushing from the body.
Uric Acid :- All animals that evolved in very dry environments , mostly terrestrial animals excrete their waste in the form of uric acid as their is lack of water already in the dry regions . Uric acid needs less water to be expelled out of body but it requires more metabolic energy to build than either ammonia or urea.
