the results indicate that ( a ) the proton-translocation activity ( membrane energization ) is enhanced in aged cell suspensions , ( b ) intactness of the cytoplasmic membrane is essential for establishing a protonmotive force in cells , ( c ) the fluorescence increase and proton translocation are reversible processes , ( d ) inhibitors of electron transport may also act as proton conductors by altering the integrity of the cytoplasmic membrane .
