Detailed explanation-1: -Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits.

Detailed explanation-2: -The enzyme speeds up the reaction by lowering the activation energy needed for the reaction to start.

Detailed explanation-3: -In enzyme-catalyzed reactions, the enzymes lower the activation energy needed for a certain chemical reaction.

Detailed explanation-4: -An enzyme is a biological catalyst. It speeds up a reaction by lowering or reducing the activation energy of the reaction. It can increase the rates of both forward and backward reactions. However, it itself does not take part in the reaction.

Detailed explanation-5: -Enzymes lower the activation energy of a reaction-that is the required amount of energy needed for a reaction to occur. They do this by binding to a substrate and holding it in a way that allows the reaction to happen more efficiently.
