WebMar 1, 2024 · The enzyme speeds up the reaction by lowering the activation energy needed for the reaction to start. Compare the activation energy with and without the enzyme. Enzymes generally lower activation energy by reducing the energy needed for reactants to come together and react. Why does a cell need enzymes? WebA catalyst lowers the barrier for the activation energy. For example, ethanol is metabolized into acetaldehyde by the enzyme, alcohol dehydrogenase. In the absence of ADH, the rate of the reaction would be less than 0.000006 (or 6 x 10-6) µmoles/L per minute. While in the presence of ADH, the reaction rate is 2700 µmoles/L per minute.
