Enzymes are specific to just one particular substrate eg. lipase can only break down fats, protease can only break down protein, and amylase is specific only to starch molecules. This is because each enzyme has a different shaped active site which matches the molecular shape of just one substance.
peptidase enzyme
Enzymes work on one substrate specifically. This is why there is millions of different types of enzymes to interact with all the molecules they need to metabolically and chemically react with.
Generally speaking, there are three classes of enzyme in our digestive system. They are listed below, alongside the molecules they break down.Lipase - lipidsCarbohydrase - carbohydratesProteases - proteins
Lipases
Proteases are enzymes which break down proteins. Each enzyme can only break down one substance (they are specific to one substrate). This is because their active site has a specific shape to fit a protein and will not fit a starch molecule.
A catalyst is a substance that speeds up a chemical reaction. Example: An enzyme, which helps break down food. There are many different types of enzymes for specific types of foods. An enzyme is a type of catalyst.
The enzyme amylase can break down starch to maltose.

Saliva contains amylase, which breaks down complex sugars such as starch. However starch can't ever be broken down into proteins. They are fundamentally different, starch is a polysaccharide while protein is a polypeptide.
Assists in the break down of starch to glucose in 3 different ways.

The body uses enzymes called amylase to break down starches. This enzyme is structured to break down the starch and no other enzyme can perform this function.
Lipases
Horses break down cellulose by use of enzyme cellulase.
Amylase
No, amylase cannot break down cellulose. Amylase is an enzyme that specifically breaks down starches, while cellulose is a complex carbohydrate found in plant cell walls that requires different enzymes, such as cellulase, to break it down.
