WebThe following enzyme activity (Michaelis-Menten) graph shows enzyme reaction rate (V) in micromoles/minute (umol/min) of product, and substrate concentration in millimolar (mM). What is the Km of the reaction? WebFactors that affect the activity of enzymes are: temperature, pH, substrate concentration and enzyme concentration. 1. THE EFFECT OF TEMPERATURE. As the temperature increases the rate of an enzyme-catalyzed reaction also increases. If the temperature is increased by 10°C, the rate of the reaction will double: Rate at x°C.
