WebMar 31, 2024 · 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 …
