Abstract
Theoretical and new experimental arguments are given to explain the reversal of photoelectric signals from purple membranes oriented and immobilized in gel due to the presence of TEMED. The continuous current induced by continuous illumination demonstrates a photoelement‐like behaviour, the polarity of which is reversed by TEMED. The data render the counterion‐collapse mechanism highly questionable.Keywords
