jpy12052-sup-0002-FigS1.epsimage/eps54KFigure S1. Model outputs to model version Ib and II. DIC in the cytosol was increased to 55 mmol · L¹ in Ib. Model version II is based on an active CO2 import into the CV. Development of DIC, TA, Ω, Ca2+ and the individual DIC species’ concentrations inside the CV during the first 0.8 s of the model run.
jpy12052-sup-0003-FigS2.epsimage/eps56KFigure S2. Model outputs to model version IIIa. Ca2+ and HCO3 cross the CV membrane independently of each other, while no H+ are exported from the CV.
jpy12052-sup-0004-FigS3.epsimage/eps140KFigure S3. Model outputs to version IV, Va, and Vb. Ca2+ and inline image are actively imported in version IV. Version V assumes an import of Ca2+, HCO3, and an export of H+, once via two transporters (V a) and once by means of one complex transporter (V b).
jpy12052-sup-0005-FigS4.epsimage/eps138KFigure S4. Results to model version VI. Ca2+ and H+ cross the CV membrane actively, after a proton gradient across the CV membrane has been established by means of an ATPase. CO2 diffuses across the membrane in both stages.
jpy12052-sup-0006-FigS5.epsimage/eps369KFigure S5. Results to model version VII. Ca²+, HCO3, and H+ actively cross the CV membrane, after the establishment of a proton gradient across the CV membrane by means of an ATPase. CO2 diffuses across the membrane in both stages. The plots on the left hand side present the whole model run, while on the right hand side, the time slot, during which the ATPase activity is stopped and the Ca2+/HCO3/H+ exchanger starts its activity, is shown in more detail.
