During N_(2) fixation, reduction of one molecule of nitrogen into 2 molecules of NH_(3) consumes _____molecules of ATP.

With regards to toxicity and the need for dilution in water, how different are ureotelic and uricotelic excretions? Give examples of animals that use these types of excretion. Ureotelism: 1. The process of excreting urea is called ureotelism. 2.Animals which are found in places where water availability is not abundant have this mode of excretion. 3. They convert Ammonia produced in the body into urea in the liver and release it to the blood. This is filtered and excreted by the kidneys, Eg: Mammals, many terrestrial amphibians and marine fishes. 4.In terms of toxicity urea is more toxic than uric acid but it is soluble in water and is thus excreted as urine.

(a) The equations given below represent the different stages of Nitrogen Cycle in plants. (i) 2NH_(3)^(+)+3O_(2)overset([A])rarr 2NO_(2)^(-)+2H^(+)+2H_(2)O (ii) 2NO_(2)^(-)+O_(2)overset([B])rarr 2NO_(3)^(-) (iii) underset("[Nitrate]")(NO_(3)^(-))overset([C])rarr underset("[Molecular Nitrogen]")(N_(2)) In the above equations [A], [B],[C] indicate the bacteria which is responsible for the reaction. Name them. (b) Define Denitrification. (c) Which enzyme is required for Nitrogen fixation ?

Identify the correct statements from the below. (I) Animals that excrete most of its nitrogen in the form of ammonia are called ammonoteles, (II) Many animals are ammonotelic (III) Mammals and terrestrial amphibians mainly excrete ammonia are called ureoteles. (IV) Earthworms, while in soil are ureoteles and when in water are ammonoteles.
