[Liberation of adenosine triphosphate after depolarization of the Torpedo electroplaque by potassium chloride].
The release of ATP after potassium depolarization was measured on fragments of electric tissue incubated in a solution containing the firefly extract. Light emission was proportional to the extracellular KCL concentration. In contrast to the release of ATP after single nerve impulses, the release after direct KCL depolarization was insensitive to curare of eserin.
