Fig. 10From: Comparative metabolic profiling of the lipid-producing green microalga Chlorella reveals that nitrogen and carbon metabolic pathways contribute to lipid metabolismThe distribution and contribution of nitrogen/carbon metabolism for lipid metabolism pathway. Black words the metabolic pathways which are related to lipid synthesis, gray words the metabolic pathways which are not related to lipid synthesis. Blue arrow N flow pathways, red arrow C flow pathways, green arrow N and C flow pathways. Solid arrow one step of metabolic flow, dotted arrow more than one step of metabolic flowBack to article page
