Work out michaelis menten kinetics instantly with clear inputs, formula shown and shareable results.
Applies the Michaelis-Menten equation, in which velocity approaches Vmax hyperbolically and equals half Vmax when substrate equals Km.
Michaelis-Menten
v = Vmax[S] / (Km + [S]); [S] = Km gives half Vmax and [S] = 9Km gives 90% of Vmax
The substrate concentration giving half-maximal velocity; a low Km means high apparent affinity.
It needs nine times Km, which is why enzymes usually operate well below saturation in cells.
