The total number of enzyme molecules per compartment is ten in all cases. Values in bold and in square brackets are those estimated by simulation; the italic values are obtained from the theoretical expressions, Eqs. (7) and (12). The parameters are: k₀ = 10⁹ s^-1 M^-1, k₁ = k₃ = 1000 s^-1, k₄⁰ = 10⁷ s^-1 M^-1, and [I] = 10 [E_T].
