Fig. 4

Steady-state distributions of all fluxes in the pathway, obtained from iterative simulations with the static model. The total fluxes include both labeled and unlabeled components of each flux and are independent of the labeling experiments. Each entry in these box plots shows the admissible range for each involved flux, with the center red line representing the median and the blue box containing the middle 50% of all admissible solutions. The partition coefficient R is factored out in this figure since it does not affect the flux profile at the steady state
