OBSERVATION OF THE ASYMMETRICAL PHENOMENA IN MEMBRANE OF FROG SARTORIUS MUSCLE FIBERS

Abstract

It has been attempted to dynamically clarify the membrane property by comparatively studying the asymmetrical phenomena taking place in the membrane of frog sartorius muscle fibers. The change in transmembrane flux, depending on the direction of membrane potential changes, was also investigated. If the same resting potential shows the existence of a constant electrical driving force, the K efflux should be equal at the same level of resting potential. But this is not always true. Moreover, in Ringer solution it is very difficult for the sites of Ca ions in the membrane to be replaced by other cations.
