Question

describe the various role of enzymes in human being

Answer 1

To facilitate reactions that require typically high activation energies. Essentially, enzymes function as organic catalysts. ... Your cells use amino acids as building blocks to createenzymes, which are then secreted by glands into the bloodstream or various cavities such as your mouth, intestines or lungs.

Answer 2

carbohydrates:
this is first digested in the mouth. the enzyme in the saliva - salivary amylase digests it first. then it passes through the stomach to the small interstine to glucose.

proteins:
the proteins are digested in the stomach by the enzyme released by the gastric glands in the walls of the stomach known as pepsin. then in the small interstine the enzyme called trypsin digests the protein further into amino acids.

fats:
the fats are also digested first in the stomach by the enzyme lipase. but at first the fats are present in the form of large globules so in order for the enzyme to act the bile salts from the gall bladder breaks the fat into smaller globules .again in the small interstine it is digested further by the enzyme lipase.
