Which of the following does not describe enzymes?
Oksanka [162]

The statement 'enzymes work by raising the energy of activation' is NOT true about the enzymatic activity. These proteins lower this energy.

Enzymes help to convert one or more reactants into specific products of the reaction that they catalyze.
