Detailed explanation-2: -Answer and Explanation: Organic substances originate from a living entity or organism, and enzymes are considered organic because they are proteins created by living things. These proteins are catalysts for reactions within the body.

Detailed explanation-3: -According to the International Union of Biochemists (I U B), enzymes are divided into six functional classes and are classified based on the type of reaction in which they are used to catalyze. The six kinds of enzymes are hydrolases, oxidoreductases, lyases, transferases, ligases and isomerases.
