Detailed explanation-1: -The name of most enzymes end with “ase". For example, a phosphatase is an enzyme that removes a phosphate group from a protein. Conversely, a kinase is a protein that adds a phosphate group to a protein. Amylase is an enzyme in our mouth that breaks down the carbohydrate starch.

Detailed explanation-2: -The names of most enzymes end in the suffix-ase.

Detailed explanation-3: -Enzymes are named by adding the suffix-ase to the name of the substrate that they modify (i.e., urease and tyrosinase), or the type of reaction they catalyze (dehydrogenase, decarboxylase). Some have arbitrary names (pepsin and trypsin).

Detailed explanation-4: -Scientists support the “lock and key” model below for how an enzyme speeds up chemical reactions. The letters “ase” at the end of words help us identify enzymes.

Detailed explanation-5: -Except for some of the originally studied enzymes such as pepsin, rennin, and trypsin, most enzyme names end in “ase".
