Solution
Enzymes:
Enzymes are proteins that function as biological catalysts.
They accelerate various chemical reactions going on in the body.
Enzymes are highly specific in their action.
Enzymes contain a substrate-binding site that has a three-dimensional structure that can only bind to its complementary substrate of a similar configuration.
Hence, every biochemical reaction taking place in the body is catalyzed by some specific enzymes.
Example - Hydrolysis of urea is catalyzed only by the enzyme urease.
Types of enzymes-
Oxidoreductase- Catalysis of oxidation and reduction reactions.
Transferases- Catalysis of reactions involving the transfer of functional groups.
Hydrolases- Catalysis of hydrolytic reactions.
Lyases- Catalysis of the reaction involving double bonds.
Isomerases- Catalysis of the reaction involving isomerization.
