Detailed explanation-1: -Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction.
Detailed explanation-2: -Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction.
Detailed explanation-3: -Definition. 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.
