For over 100 years, a major object of photobiological studies has been the unicellular flagellate, Euglena gracilis, an organism well suited for such investigations by its special complement of organelles that may be considered an ancient, yet complete “visual” system. This paper deals with the hypothesis of protein bistability oriented dipole and electroconformational coupling mechanisms as the physical phenomena that produce signal transduction. A model for phototaxis is presented.
