Fig 3. Initial rates and apical uptake experimental data and model simulations.

A) Initial iron absorption rates. B) Apical iron uptake after a 20 µM iron challenge. Circles correspond to the average value, error bars indicate standard deviation for each sample. $MM(K_m^{fit},V_{max}^{fit})/B{M}_{best}$ best biochemical model simulation (green line); Hill model (red line); $MM(K_m^{exp},V_{max}^{exp})$ model (blue line); Best GP Model (gray line) and Pruned GP Model (black line).
