Question

what is ammonotelism,ureotelism and uricotelism and what are the differences between the three

Answer 1

Ammonotelism	Ureotelism	Uricotelism
Chief nitrogenous waste is ammonia	Chief nitrogenous waste is urea	Chief nitrogenous waste is uric acid
Solubility: Easily dissolves in liver cells by deamination of aminoacids	It is less soluble in water	It is almost insoluble in water.
Ammonia is formed by deamination of amino acids in liver cells	Urea is formed in liver and is produced from an amino acid arginine. Arginase is the enzyme involved.	Potassium ureate reacts with water and carbon dioxide to form uric acid
Ammonia is very toxic	Urea is less toxic	Uric acid has very low toxicity
