Enzymes are biological catalysts. catalysts are proteins that increase the rate of chemical reactions without being used up.

for example : amylase catalyses the breakdown of starch into sugar in the mouth and small intestine

Enzymes:

Enzymes are proteins that act as biological catalysts in chemical reactions. They are essential for the proper functioning of living organisms as they speed up the rate of chemical reactions without being consumed in the process. Enzymes are specific in their action and are required in small amounts to carry out their functions.

Enzyme of digestive system:

One enzyme of our digestive system is amylase. Amylase is an enzyme that breaks down complex carbohydrates into simple sugars like glucose, fructose, and maltose. It is produced in the salivary glands, pancreas, and small intestine.

Functions of amylase:

Amylase is important for the digestion and absorption of carbohydrates in our body. It plays a vital role in breaking down starch and glycogen, which are complex carbohydrates, into simple sugars that can be easily absorbed by the body.

The process of digestion starts in the mouth, where amylase is secreted by the salivary glands. It initiates the breakdown of carbohydrates into smaller molecules, which can be further broken down in the small intestine. The pancreas also secretes amylase into the small intestine, where it helps in the final breakdown of carbohydrates into simple sugars.

Conclusion:

In summary, enzymes are essential proteins that act as biological catalysts in chemical reactions. They are specific in their action and are required in small amounts to carry out their functions. Amylase is an important enzyme of our digestive system that plays a vital role in the breakdown of complex carbohydrates into simple sugars that can be easily absorbed by the body.
