Web13 nov. 2024 · S + E ⇌ ES → P + E. Two important terms within Michaelis-Menten kinetics are: Vmax – the maximum rate of the reaction, when all the enzyme’s active sites are saturated with substrate. Km (also known as the Michaelis constant) – the substrate concentration at which the reaction rate is 50% of the Vmax. Km is a measure of the … WebThus, to analyze our data using this equation we need to take the inverse of the substrate concentration and the inverse of the initial rate and fit them to the equation of a line. This …
