Before revision:  In addition, FFP maps are able to uncover metabolic behaviors, such as aerobic glycolysis in high-growth minimal medium with unlimited oxygen uptake , that are unreachable using  models based on optimality principles.
After revision:  In addition, FFP maps are able to uncover metabolic behaviors, such as aerobic fermentation accompanying exponential growth on sugars at nutrient excess conditions , that are unreachable using models based on optimality principles.
