Michaelis–Menten enzyme kinetics (initial rate vs substrate) (v = Vmax[S] / (Km + [S]))
jee-mainjee-advancedneet-ug
v = Vmax[S] / (Km + [S])
What each symbol means
| Symbol | What it stands for |
|---|---|
| v | Initial reaction velocity |
| Km | Michaelis constant (substrate at half Vmax) |
| [S] | Substrate concentration |
| Vmax | Maximum velocity (enzyme saturated) |
When to use this
Steady-state Briggs–Haldane assumptions; single-substrate Michaelis–Menten form as in JEE biochemistry drills.
