Parameters
Vmax (max reaction rate)
μmol/min
Km (Michaelis constant)
μM
Key Concepts
• v = Vmax × [S] / (Km + [S]) — hyperbolic curve
•
Km
= substrate concentration at v = Vmax/2
• Low Km → high affinity (enzyme reaches half-max at low [S])
• At high [S], all enzyme active sites are saturated → v → Vmax
