colour.biochemistry.reaction_rate_MichaelisMenten(S: FloatingOrArrayLike, V_max: FloatingOrArrayLike, K_m: FloatingOrArrayLike, method: Literal['Michaelis 1913', 'Abebe 2017'] | str = 'Michaelis 1913', **kwargs: Any) → FloatingOrNDArray[source]#

Describe the rate of enzymatic reactions, by relating reaction rate \(v\) to concentration of a substrate \(S\) according to given method.

Parameters:

  • S (FloatingOrArrayLike) – Concentration of a substrate \(S\).

  • V_max (FloatingOrArrayLike) – Maximum rate \(V_{max}\) achieved by the system, at saturating substrate concentration.

  • K_m (FloatingOrArrayLike) – Substrate concentration \(K_m\) at which the reaction rate is half of \(V_{max}\).

  • method (Literal['Michaelis 1913', 'Abebe 2017'] | str) – Computation method.

  • b_m – {colour.biochemistry.reaction_rate_MichaelisMenten_Abebe2017()}, Bias factor \(b_m\).

  • kwargs (Any) –

Returns:

Reaction rate \(v\).

Return type:

numpy.floating or numpy.ndarray
