Profiles of the metabolic intermediates in starch and lipid synthesis. a Synthetic pathway of starch and lipid by CO2 fixation in Chlamydomonas spp. S7P sedoheptulose 7-phosphate, Ru5P ribulose 5-phosphate, 3PGA 3-phosphoglycerate, F6P fructose 6-phosphate, G6P glucose 6-phosphate, G1P glucose 1-phosphate, PEP phosphoenolpyruvate, AcCoA acetyl-CoA G3P, glycerol 3-phosphate. Reactions containing multiple enzymatic steps are represented by dotted lines. b Pool size of the metabolic intermediates under the continuous light and light/dark conditions. Red dotted line with open circle and dark blue line with closed circle indicate the continuous light (LL) and light/dark (LD) conditions, respectively. Error bars indicate the SD of three replicate experiments (*p < 0.05 by Student’s t test)
