saadhussain514 · Answer

The correct answer is:b.They occur more quickly than reactions without enzymeExplanation:Catalysts decrease the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes further up reactions by reducing activation energy. Many enzymes change shape when substrates bind.
