Question

what are enzyme? mention any four types of enzyme based on function

Answer 1

Enzymes are the proteins that control the speed of metabolic reactions in our body. Without enzymes , these reactions would take place too slowly to keep us alive. They accelerate many metabolic reactions. That is why they are known as biochemical catalyst.

Salivary glands: The salivary glands secrete the first of the digestive juices, the saliva. In the digestion process, the saliva helps the teeth and tongue to masticate and mix up the food thoroughly.

Pancreas: It is a soft lobulated gland present in between the loops of duodenum. It secretes pancreatic juice containing enzymes which is poured into duodenum with a help of pancreatic duct.

Liver: It is the largest gland in human. Liver secretes bile, the digestive juice, which is temporarily stored in the gall bladder.The bile juice plays an important role in the digestion of fats.

Small intestine :- It secretes the intestinal juices which help in further digestion of food which is to be released to the large intestine.

Answer 2

Enzymes are proteins that are created by living organisms and are responsible for a variety of metabolic and biochemical events in the body.  

There are six types of biochemical reactions that occur in the body, and the enzymes that cause these reactions are named after them:

• Oxidoreductases are enzymes that catalyse both oxidation and reduction processes.

• Transferases are enzymes that help molecules transfer functional groups from one to another.

• Hydrolases are enzymes that catalyse processes involving the hydrolysis process.
• Lyases catalyse processes in which functional groups are introduced to break double bonds in molecules or where functional groups are removed to generate double bonds.

• Isomerases catalyse processes in which a functional group is transferred to a different place within the same molecule, resulting in a molecule that is an isomer of the previous molecule.

• Ligases are enzymes that do the opposite of hydrolases in terms of function. Ligases build bonds by removing the water component, whereas hydrolases break bonds by adding water.
