Michaelis–Menten Enzyme KineticsLive

how enzymes saturate

Controls

Presets

Vmax (µmol/min)

Km (mM)

Substrate [S] (mM)

Enzymes speed reactions but saturate: as substrate rises, the rate approaches a ceiling Vmax. Km — the substrate level giving half Vmax — measures how tightly the enzyme binds. Low Km means high affinity. Educational tool.

Reaction rate v50.0 µmol/min

Fraction of Vmax50%

Km (half-Vmax [S])5 mM

Governing equation

v = \frac{V _{ma x} [ S ]}{K _{m} + [ S ]} = \frac{100 \cdot 5}{5 + 5} = 50.0 μ mol/min

Reading this result: At [S] near Km (5 mM) the enzyme works at about half speed (50% of Vmax) — this is the steepest, most substrate-sensitive part of the curve.
