Function of enzymes in catalyzing biological reactions Enzymes are catalysts, which are things that increase the rate of a reaction, but does not get used up during the reaction. Structure determines function. A change in structure => a change in function. Important biological reactions catalyzed by enzymes: Metabolism.
The enzyme's shape fits its substrate's shape, thus allowing the enzyme to catalyze the appropriate reaction.
