Abstract
The effects of heating, organic solvents and detergents on the light-dependent hydrogen ion uptake in chloroplasts and chromatophores and the coupled photophosphorylation were compared. It was shown that the membrane structure of the chromatophores is much more stable than that of the chloroplast thylacoids. The activation of the pH function in the chromatophores in the presence of low concentrations of diethyl ether and detergents was noted. The effects observed may be due to the changes in the physico-chemical properties of the membranes rather than to the direct effect on the photosynthetic electron transfer chain.
