Examples
Lipase - fats and oils - Glycerol and fatty acids.
Amylase - starch - maltose
Pepsin - protein - polypeptides
lactase, catalase, amylase are all examples of enzymes
caralase is one of the most common enzymes in living things and breaks down substrates like H202(hydrogen peroxide), a potentially harmful chemical formed in cells.
Models
Induced fit- A model for enzyme-substrate interaction to describe that only the proper substrate is capable of inducing the proper alignment of the active site that will enable the enzyme to perform its catalytic function.
Lock&Key- The substrate fits perfectly in the enzyme and unlocks it so that it will work. This model fits unlike the other.
Coenzymes
A nonprotein component of enzymes is called the cofactor. If the cofactor is organic, then it is called a coenzyme. Coenzymes are relatively small molecules compared to the protein part of the enzyme. Many of the coenzymes are derived from vitamins.
The coenzymes make up a part of the active site, since without the coenzyme, the enzyme will not function.
