WebbKm = Michaelis constant. Although Km values are more or less constants for particular enzyme-substrate systems, but these may vary slightly with pH, temperature, ionic … Webb2 feb. 2024 · The Michaelis constant describes the kinetics of substrate/enzyme binding. However, its precise meaning depends on what assumptions are made when deriving the equation. Reviewing the derivations of the Michaelis-Menten equation is essential to clarify this. We begin by expressing the rate of product formation (v0).
