Direct measurements of intracellular K+ and Cl-activities before and after blockage of cellular metabolic processes indicate that K+ is actively transported inwardly and Cl-is actively transported outwardly from the giant cell of the abdominal ganglion of Aplysia. The rewarming of cells that have been cooled to 1° ± 1°C causes K+ to be taken up and Cl- to be extruded against electrochemical gradients.
