TABLE 5.

Ratio between cytoplasmic and external concentrations of solute under conditions of dynamic balance when the rates of inward permeation and efflux become equal

^aThe models correspond to those described in the legend to Fig. 4.

^bAbbreviations: OM, outer membrane; CM, cytoplasmic membrane.

^cc₃ and c₁ are the concentrations of the solute in the cytoplasm and external medium, respectively. The periplasmic concentration, c₂, was eliminated by substitution in deriving the equations. For other symbols, see Fig. 4 and Table 1.
