Abstract
The membrane potential and the ionic activity gradients of K+ and Cl− across the surface membrane of cytoplasmic droplets prepared from Chara australis internodal cells, were measured in high and low ionic strength bathing solutions using liquid ion exchange microelectrodes selective for K+ and Cl−. Our results indicate that K+ is close to electrochemical equilibrium whereas Cl− is not.This publication has 8 references indexed in Scilit:
