Figure 5.

Model results. The model structure diagram (A) illustrates the active fluxes (solid arrows), passive fluxes (dashed arrows), and CO₂/HCO₃⁻ interconversion (double-headed arrows) in the CCM, with the parameters controlling these fluxes indicated above each arrow (for notation, see Table III). Agreement of the various models with photosynthesis (P) and CO₂ flux (Cup) data (B) and the internal C_i pool (C) is shown. Inferred carboxysome CO₂ concentrations were calculated as described in “Results.”
