Fig. 7. The probability distribution of Km1, Km2, kcat1, and kcat2 estimates. (A) Km1 at 1%, 5% and 10% error. (B) kcat1 at 1%, 5%, and 10% error. (C) Km2 at 1%, 5%, and 10% error. (D) kcat2 at 1%, 5%, and 10% error. The probability distribution for all parameters is depicted for the Michaelis-Menten equation (red), ESS velocity equation (blue), ES ODE (green), ESS ODE (purple), ESP1P2 ODE (orange), and ESSP1P2 ODE (magenta). Distribution is shown for 500 runs at each condition. Data were simulated with the following parameters: k1 = k5 = 270 µM−1 min−1, k2 = 13,500 minute−1, k3 = 1 minute−1, k4 = 1 minute−1, k6 = 2700 minute−1, k7 = 5 minute−1, k8 = 1 minute−1.
