  • Abstract There are five major electroenzymes in the plasmalemma of plant cells: a driving electrogenic pump, inward and outward rectifying K+ channels, a Cl−-2H+ symporter, and Cl−-channels. It has been demonstrated previously (Gradmann, Blatt & Thiel 1993, J. Membrane Biol.136:327–332) how voltage-gating of these electroenzymes causes oscillations of the transmembrane voltage (V) at constant substrate concentrations. The purpose of this study is to examine the interaction of the same… CONTINUE READING
