Question

The nitrogenous products of the breakdown of proteins are excreted as ammonia, urea and uric acid. Explain the difference in each of these products in terms of amount of water conservation, toxicity and energy required. Give an example of an animal that would excrete each type of substance.

Answer 1

The protein that are intake through foods are broken down in the body and is converted into nitrogenous waste products which are eliminated from the body through the process of excretion.

Step-by-step explanation:

Ammonotelic-Those organisms that excrete nitrogenous waste products in the form of ammonia from the body throuh the process of excretion is called as ammonotelic animals.Ammonia is more soluble in water.

Ex- Bony fish, Octopus, Sepia etc.

Ureotelic-Those organisms that excrete nitrogenous waste products in the form of Urea from the body through the process of excretion is called as Ureotelic organisms.Urea is soluble in water.

Ex- Human.

Uricotelic-Those organisms that excrete nitrogenous waste products in the form of Uric acid from the body through the process of excretion is called as uricotelic organisms.Uric acid is insoluble in water.

Ex- Reptiles, birds etc.
