Abstract

Conductance to K⁺ alters as a function of membrane potential (Ψ_m). Conductance to H⁺ (or OH^-) changes with external pH (pH^o) This conductance change can be modulated by altering cytoplasmic pH or external K⁺ concentration, both of which also alter Ψ_m. We suggest a role for H⁺ conductance in regulating cytoplasmic pH above pH^o 7.0.
