The dual nature of the membrane potential increase associated with the activity of the sodium/potassium exchange pump in skeletal muscle fibres

Abstract

Results are presented which suggest that the contribution to the membrane potential in frog skeletal muscle evoked by ionic pump activity is made up of two components. One of these is directly related to the ‘electrogenic’ mode of pump action; the other, of similar magnitude, is an indirect effect due to potassium depletion in the lumen of the T -tubular system. The extent of this depletion has been estimated.
