What is the Enzyme Pathway multi-solver?

Enzyme Pathway is a guided workflow that chains 1 individual PolySim solvers into one end-to-end analysis, piping each result into the next step.

Yes. Every step runs entirely in your browser using real numerics — no install, no account, no cloud cost. Custom or private solver packs are available as a paid service.

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.

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.
