Detailed explanation-1: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction.
Detailed explanation-2: -Enzymes perform the critical task of lowering a reaction’s activation energy-that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.
Detailed explanation-3: -Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction.
Detailed explanation-4: -Enzymes generally lower activation energy by reducing the energy needed for reactants to come together and react. For example: Enzymes bring reactants together so they don’t have to expend energy moving about until they collide at random.
Detailed explanation-5: -Enzymes allow activation energies to be lowered. Enzymes lower the activation energy necessary to transform a reactant into a product.
