Detailed explanation-1: -Enzymes serve as catalysts to many biological processes, and so they are not used up in reactions and they may be recovered and reused.

Detailed explanation-2: -Enzymes let chemical reactions in the body happen millions of times faster than without the enzyme. Because enzymes are not part of the product, they can be reused again and again.

Detailed explanation-3: -At the end of the reaction, the product/s are formed, the enzyme remains unchanged, can bind another substrate and can be reused many times. Active site or catalytic site is the specific place in the enzyme where the substrate binds.

Detailed explanation-4: -An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is used over and over.

Detailed explanation-5: -Enzymes speed the reaction, or allow it to occur at lower energy levels and, once the reaction is complete, they are again available. In other words, they are not used up by the reaction and can be re-used.
