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 substrate ms bind.
        
             
        
        
        
Cell replication is meant to be a very regulated process. Messages are sent to the cell, telling it when to duplicate and when not to. When cells divide according to their natural plan, then there are no problems. However, when cells either do not receive those messages or misinterpret them, they can divide too fast and without pause. These renegade cells are what we call cancer cells.
