Dual price sensitivity of uptake fluxes for 6 non-essential nutrients in response to 17 nutrient exchange fluxes for CHO-DG44, -K1 and -S during early exponential phase. Positive and negative values represent increase or decrease, respectively, of uptake requirement in response to increasing consumption of amino acids and glucose. x-axis: Increase in 1 unit of specific amino acid or glucose availability; y-axis: Resulting increase/decrease of each nutrient uptake requirement
