enzymes are biological catalysts quizlet

Share. An enzyme is a biological catalyst, a substance that increases the rate of a chemical reaction without being changed or consumed in the reaction. They perform this role in ways that differ from reaction to reaction but, in every instance, catalysis proceeds through the formation of complexes between the enzyme and the reactants. Enzymes initiate and accelerate the rate of biochemical reaction.
