Effect of anion substitutions on the chord conductance-voltage (G–V) relationship. Chord conductances in the presence of 140 mM Cl⁻ and 140 mM anion substitutes were calculated as a function voltage on a cell-to-cell basis from the data in Fig. 2. A: SCN⁻ (n = 8). B: ClO₄⁻ (n = 9). C: $N{O}_3^{-}$ (n = 20). D: I⁻ (n = 8). E: Br⁻ (n = 8). F: gluconate (n = 9).
