Figure 6.

Comparison of the predicted NADPH flux during photosynthetic or aerobic respiratory growth. Predictions were made for the total NADPH flux during growth with succinate, glucose and acetate under photosynthetic and aerobic respiratory conditions. The error bars represent the standard error of mean of 1000 fluxes through this reaction obtained from 1000 alternative optimal solutions (see Methods). It should be noted that the predicted larger NADPH demand under aerobic conditions compared to photosynthetic conditions during growth with acetate is due to a larger predicted uptake rate of acetate under aerobic conditions.
