Abstract : Oxygen is shown to enhance the light-induced proton uptake capability of spinach chloroplasts. Additional studies have also shown that oxygen is able to restore the light-induced pH rise of dithionite-treated chloroplasts. Similar results observed when oxygen is replaced by p-benzoquinone suggest that the effect of oxygen to enhance and restore the pH rise is related to its ability to pose the redox components of the electron transfer chain for maximum pH rise.
