Michaelis–Menten Enzyme KineticsLive
how enzymes saturate
Controls
Presets
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
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.
