Example use cases of the map. Visualization of the difference in flux distribution when growing in the presence (A) or absence (B and C) of light. When light is present (A), the FBA solution harbors no surprises. However, when light is absent (B), FBA predicts that photorespiration is active, which is unlikely. C, Adding a reaction that converts l-Pro to Hyp returns the model to its expected state under dark conditions. Note that some glyoxylate is still produced from other precursors than glycolate (not shown here) to enable the production of amino acids.
