GENERAL KNOWLEDGE

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: -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.

Detailed explanation-3: -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-4: -Enzyme increases the rate of reaction by lowering the activation energy. Explanation: Activation energy is the difference in free energy between the reactants and transition state. To complete a reaction, enzyme lowers the activation energy and crosses the transition state.

Detailed explanation-5: -Enzymes speed up a chemical reaction by lowering the activation energy required for the reactants to come together and react. Activation energy refers to the energy that is needed to trigger a chemical reaction between two or more reactants.
