The primary photosynthetic reactions in isolated pea chloroplasts with the structures fixed by increasing concentrations of glutaric aldehyde were studied. It was shown that under chloroplast fixation by 5--25 mM of glutaric aldehyde, a significant inhibition of processes responsible for energy transformation in biological membranes was observed. The highest sensitivity was observed for the phosphorylation reactions, photo-induced changes in absorption at 520 nm, photo-induced quenching of atebrin fluorescence and slow component of delayed light emission. The photo-induced proton uptake was found to be less sensitive to fixation by glutaric aldehyde. It was also shown that on chloroplast fixation the extent of the steady-state P700 oxidation and the lifetime of the photosystem I and II chlorophyll fluorescence are both increased, a fact is indicating of loss in the effectiveness of light energy transfer from the antenna molecules to the reaction centres. Presumably the conformational changes play an essential role at the initial steps of light energy transformation.
