GENERAL KNOWLEDGE

Detailed explanation-1: -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-2: -Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

Detailed explanation-3: -Enzymes work as catalysts in a chemical reaction, speeding up the process by lowering the energy of activation. This means that enzymes reduce the amount of energy required to make the reaction occur, making it a faster and more efficient reaction.

Detailed explanation-4: -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-5: -Desolvation or taking reactants out of the solution state. Establishing weak bonds between the reactants and enzyme. Bringing the reactant molecules closer in the region of the active sites of enzymes. Development of strain in the bonds of the reactants by the electrophilic and nucleophilic attack.
