  1. The results show several approaches in the 3 - phosphoglycerate sink implementation and its consequence on the system efficiency (total mass production), regulation and content of the pool of metabolites as well as the changes within the Calvin-Benson after 3 hours of simulation (from dynamic changes to steady state conditions). The numbers indicates percentage changes in comparison to corrected Zhu model (100%), Matlab version. The response of system to the changes has been tested by using the original Zhu model (values in the brackets) which has significantly different equilibrium in comparison to the corrected model versions. Meaning of particular abbreviations: C-B pool - metabolic pool of the Calvin-Benson cycle, A - Appendix A model version, M - Matlab model version, MA - Mass action law kinetics, MM -Michaelis-Menten kinetics (phosphate translocator), cb - designed for cyanobacteria. The bold font indicates the highest value.
