Understanding This Calculator

Michaelis-Menten Equation

Relates reaction rate (v) to substrate concentration [S].

v = (Vmax × [S]) / (Km + [S])

Example 1

Vmax=100, [S]=0.01, Km=0.01

  • [S] = Km -> v should be Vmax/2
  • v = (100 × 0.01) / (0.01 + 0.01) = 1 / 0.02 = 50

Example 2

Vmax=100, [S]=99Km

  • v ≈ 0.99 Vmax

How to Use

  • Enter Vmax, substrate concentration, and Km.
