Analysis of the outputs from the Calvin-Benson cycle based on the Poolman model. This analysis shows the difference between the original Poolman model  and the revised version in which the rate equation E17 has been modified (replacement of Pi_ch by starch). This modification solved the problem with negative concentration of the starch. Dotted line stands for the original Poolman model, solid line for the modification/correction. Meaning of the colors: red - starch, black - GAP in cytosol, green - PGA in cytosol, blue - DHAP in cytosol.
