The statement 'enzymes work by raising the energy of activation' is NOT true about the enzymatic activity. These proteins lower this energy.
<h3>Enzymes and activation energy</h3>
Enzymes are proteins capable of catalyzing specific chemical reactions in a given medium.
Enzymes work by lowering (instead of increasing) the activation energy of a chemical reaction.
Enzymes help to convert one or more reactants into specific products of the reaction that they catalyze.
