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.
Detailed explanation-2: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction. The increased rate is the same in both the forward and reverse directions, since both must pass through the same transition state.
Detailed explanation-3: -Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.
Detailed explanation-4: -Enzyme: 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.
