Naming:

• Substrate and the suffix ase i.e. lipase, urease

• Reaction and the suffix ase i.e. isomerase, oxidase

• Substrate and reaction and the suffix ase i.e. alcohol dehydrogenase, pyruvic

acid decarboxylase.

Classification:

1. Hydrolytic enzymes (hydrolases)

2. Oxidation reduction enzymes (Oxidoreductases)

3. Transferases which catalyze the transfer of specific group (s) from one molecule

into another.

4. Carboxylases, which assist the process of carboxylation or decarboxylation of

the substrate.

5. Addition enzymes i.e., which responsible for the addition or removal of certain

molecules to the substrate e.g., hydrases.

(Factors affecting enzyme action|)

1- Substrate and enzyme concentrations

2- Temperature

3- Medium PH:

• Basic pH e.g., Arginase
• Neutral pH e.g., Salivery amylase

• Acidic pH e.g., pepsin
