Question

The enzyme which catalyses the formation of glutamine from its substrate belongs to category
a. Hydrolases
b. Transferases
c. Ligases
d. Lyases

Answer 1

Hint: It is utilized in cells to hitch along the Okazaki fragments that area unit fashioned on the insulation strand throughout desoxyribonucleic acid replication.

Complete Answer:
a. Hydrolases square measure enzymes that turn the cleavage of a chemical bond victimisation water. styles of hydrolase embody esterases, like phosphatases, that act on organic compound bonds, and proteases or peptidases that act on organic compound bonds in peptides.

b. An enzyme is anybody of a category of enzymes that enact the transfer of specific practical teams from one molecule to a different one. they're concerned in many completely different organic chemistry pathways throughout biology, and square measure integral to a number of life's most vital processes.

c.Glutamine is created as a results of ligature reaction involving the condensation of salt and ammonia. The reaction is catalysed by protein amino alkanoic acid synthetase that could be a variety of ligase and plays a vital role within the metabolism of N. Ligases square measure a class of enzymes that turn the linking along of 2 compounds. The protein utilizes ammonia created from amino alkanoic acid degradation and hotoresiration. The reaction involves the adenosine triphosphate dependent condensation of ammonia with salt.

d. A lyase is an associate degree protein that catalyzes the breaking of varied chemical bonds by suggesting that apart from reaction and reaction, usually forming a brand new covalent bond or a brand new ring structure. The reverse reaction is additionally potential

Hence option:c is the correct answer.

Note: Out of all mammalian DNA ligases, only Lig III has been found to be present in mitochondria.
