Expert Solution
Step 1

Enzymes are usually proteinaceous substances that act as catalysts for biological reactions. Hence, they are also called biological catalysts or biocatalysts. 

There are six main classes of enzymes. They are oxidoreductases, transferases, hydrolases, lyases, isomerases, and ligases.
