Abstract. The function of an enzyme is to catalyze a chemical reaction. The progress of the catalysis can be followed by quantitative measurements of the rate of formation or disappearance of the molecules participating in the reaction. Investigation of the rate of catalysis under various conditions contributes to a clarification of the ...Kinetics. The rates of enzyme-catalysed reactions vary with pH and often pass through a maximum as the pH is varied. If the enzyme obeys Michaelis-Menten kinetics the kinetic parameters k 0 and k A often behave similarly. The pH at which the rate or a suitable parameter is a maximum is called the pH optimum and the plot of rate or parameter against pH is called a pH profile.
