Abstract

The effects of bicarbonate ions on the membrane potential and resistance ofNitella translucens are shown to be primarily due to the change in pH produced by the bicarbonate acting as a buffer, and not due to the presence of an electrogenic anion pump. The mechanism by which pH affects the membrane potential is discussed in the context of recent work by other authors on this effect.
