Why does the activation energy of many reactions in living systems need to be reduced for living systems to function? decrease activation energy to make the chance of reaction occurring more likely. Compare the “lock-and-key” model of enzyme function with the “induced fit” model of enzyme function.Click to see full answer. Consequently, how is activation energy lowered?A catalyst is something that lowers the activation energy; in biology it is an enzyme. The catalyst speeds up the rate of reaction without being consumed; it does not change the initial reactants or the end products.Likewise, why do enzymes lower the activation energy? Enzymes lower the activation energy of a reaction by binding one of the reactants, called a substrate, and holding it in a way that lowers the activation energy. Likewise, an enzyme holds its substrate in such a way that the reaction is much more likely to occur. Just so, why does the activation energy of many reactions need to be reduced? 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. Many enzymes change shape when substrates bind.Why is activation energy important?All chemical reactions, including exothermic reactions, need activation energy to get started. Activation energy is needed so reactants can move together, overcome forces of repulsion, and start breaking bonds.
