The review summariezes current data about the origin of membrane potentials and their contribution to the
signal transduction about changes in temperature, ionic composition of the medium, and chemo-, photo-, gravitaxis
signals in unicellular eukaryotes.
Key words: unicellular eukaryotes, intracellular signaling, membrane potential, ionic channels,
intracellular calcium
