Question

Nitrogenous waste which is less toxic , soluble in water and formed during Ornithine cycle is ______a) urea b) uric acid
c) ammonia
d) amino acid

Answer 1

Urea is less toxic substance formed during ornithine cycle and soluble in water.

Answer 2

Answer:

a) urea

Explanation:

Nitrogenous waste which is less toxic, soluble in water and formed during the Ornithine cycle is urea. Urea is the excretory product of mammals which is soluble in water and less toxic. Ornithine cycle is also known as urea cycle in which urea is formed from ammonia by some chemical reactions. Urea is soluble in water.

Ammonia is highly toxic nitrogenous waste excreted by bony fishes and frogs (in water).

Uric acid is not a very toxic nitrogenous waste but insoluble in water. It is the excreted by most reptiles, insects, and birds.

The amino acid is not a nitrogenous waste.
