Question

write name of any three enzymes and write their function? plzz tell me​

Answer 1

Answer:

Explanation:

Oxidoreductases: These enzymes bring about oxidation and reduction reactions and hence are called oxidoreductases. In these reactions, electrons in the form of hydride ions or hydrogen atoms are transferred. When a substrate is being oxidized, these enzymes act as the hydrogen donor. These enzymes are called dehydrogenases or reductases. When the oxygen atom is the acceptor, these enzymes are called oxidases.

Transferases: These enzymes are responsible for transferring functional groups from one molecule to another. Example: alanine aminotransferase which shuffles the alpha‐amino group between alanine and aspartate etc. Some transferases also transfer phosphate groups between ATP and other compounds, sugar residues to form disaccharides such as hexokinase in glycolysis.

Hydrolases: These enzymes catalyze reactions that involve the process of hydrolysis.They break single bonds by adding water. Some hydrolases function as digestive enzymes because they break the peptide bonds in proteins. Hydrolases can also be a type of transferases as they transfer the water molecule from one compound to another. Example: Glucose-6-phosphatase that removes the phosphate group from glucose-6-phosphate, leaving glucose and H3PO4.

Answer 2

Answer:

Enzymes are protein molecules that act as a biological catalysts in our digestive system. In our digestive system, Different enzymes are there to digest the different components of food.

for example,  

=> Amylase : It is a carbohyadrate splitting enzyme present in saliva in mouth as well as small intestine. It hydrolysed the starch into a Disaccharides.  

=> Lipase : It helps for the digestion of lipids . It breakdown the fat into diglycerides and monoglycerides.

=> pepsin : The group of these enzymes include trypsin, chymotrypsin and carboxypeptidase which breakdown the Proteins, peptons and proteoses into Dipeptides  

=> Nucleases : These enzymes acts on nucleic acids and converted it into nucleotides and nucleosides.
