Maximum Reaction Velocity - an overview ScienceDirect Topics
WebbOn a V vs. [S] plot, Km is determined as the x value that give V max/ 2. A common mistake students make in describing V max is saying that Km = Vmax/2. This is, of course not true. Km is a substrate concentration and is the amount of substrate it takes for an enzyme to reach V max /2. WebbMichaelis constant.

Webb31 dec. 2024 · Where Vmax is the maximum velocity ( [E]T*kcat), [S] is the substrate concentration, and Km is the Michaelis constant. Without any competitive inhibitor, the initial velocity (v0) simplifies to typical Michaelis-Menten kinetics: The IC50 concentration is reached when the ratio of the inhibited to the uninhibited reaction rate is 50%: Webb26 jan. 2024 · Deriving from Michaelis-Menten equation: kM= (k-1+kcat)/k1.
