Temperature plays an important role in enzymatic activity because it speeds up the reaction. However, if there is too much of an increase in heat, this can cause the enzyme to denature from its quaternary structure back to its primary structure. If the temperature decreases and reaches the enzymes optimal temperature, then the enzymes shape can be regained. Enzymes also have an optimal pH or pH range enhance the ability of catalytic reactions. If there is an increase or decrease from the optimal pH or pH range, the enzyme will denature and like temperature, it must reach its optimal environment (pH) in order to return back to its quaternary structure. Through experiments, if the concentration of the substrate increases gradually as the enzyme is kept constant, the substrate concentration gradually increases until the maximum velocity or Vmax is reached as shown in the image to the right.
