title: CHANGES OF APPARENT IONIC MOBILITIES IN PROTOPLASM : IV. INFLUENCE OF GUAIACOL ON THE EFFECTS OF SODIUM AND POTASSIUM IN NITELLA.
abstract: In Nitella, as in Halicystis, guaiacol increases the mobility of Na(+) in the outer protoplasmic surface but leaves the mobility of K(+) unaffected. This differs from the situation in Valonia where the mobility of Na(+) is increased and that of K(+) is decreased. The partition coefficient of Na(+) in the outer protoplasmic surface is increased and that of K(+) left unchanged. Recovery after the action current is delayed in the presence of guaiacol and the action curves are "square topped."
