Question

What is the difference between Ammonotelism, Ureotelism and Uricotelism?

Answer 1

Ammonotelism vs Ureotelism vs Uricotelism

Ammonotelism

1. Chief nitrogenous waste is ammonia.

2. Solubility: Easily dissolves in liver cells by deamination of aminoacids.

3. Ammonia is formed by deamination of amino acids in liver cells.

4. Ammonia is very toxic

Ureotelism

1. Chief nitrogenous waste is urea

2. It is less soluble in water.

3. Urea is formed in liver and is produced from an amino acid arginine. Arginase is the enzyme involved.

4. Urea is less toxic

Uricotelism

1. Chief nitrogenous waste is uric acid

2. It is almost insoluble in water.

3. Potassium ureate reacts with water and carbon dioxide to form uric acid.

4. Uric acid has very low toxicity
