Enzymes play an important role in regulating metabolic pathways in the human body and without enzymes they will not function efficiently.
The rate of a reaction is enhanced by enzyme activity which provides alternate pathways for the reaction to proceed by. The specificity of enzymes helps make them powerful tools in nature; they are allowed to form enzyme-substrate complexes. (Bioinfo.org.cn, 2015)
Reaction rates controlled by enzyme can be measured using experimental methods where the factors such as enzyme, pH and temperature can be studied. These results can be
