Lineweaver-Burk plot

Michaelis-Menten kinetics describe how reaction rate rises with substrate and saturates at Vmax. Km is the substrate concentration giving half-maximal rate — a measure of enzyme affinity. A competitive inhibitor raises the apparent Km without changing Vmax, seen as a shift in the double-reciprocal Lineweaver-Burk line.

Data Inspector

Vmax100

Apparent Km5.0

v at [S]=Km50.0

Governing equation

v = \frac{V _{ma x} [ S ]}{K _{m} + [ S ]} = \frac{100 [ S ]}{5.0 + [ S ]}

Reading this result: With Km 5, the rate hits half of Vmax (100) at [S]=5; pushing substrate well past Km barely raises v as the curve flattens toward saturation.
