Oxygen Concentration in Isolated Chloroplasts during Photosynthesis.
The O(2) concentration in intact and osmotically disrupted isolated spinach (Spinacia oleracea, L.) chloroplasts during photosynthesis was estimated. The chloroplasts were allowed to reduce 3-phosphoglycerate, CO(2), or ferricyanide in light until the rate of O(2) production was linear. When the light was turned off O(2) evolution from the chloroplasts continued for a few seconds. This prolonge...

متن کاملInhibition of photosynthesis by oxygen in isolated spinach chloroplasts.
The inhibition of photosynthetic CO(2) fixation by O(2), commonly referred to as the Warburg effect, was examined in isolated intact spinach (Spinacia oleracea) chloroplasts. The major characteristics of this effect in isolated chloroplasts are rapid reversibility when O(2) is replaced by N(2), an increased inhibition by O(2) at low concentrations of CO(2) and a decreased effect of O(2) with in...
متن کاملPhotosynthesis by isolated chloroplasts.
Photosynthesis in green plants requires not only photoelectron transport, oxygen evolution, and photophosphorylation, but also the synthetic reactions whereby carbon dioxide is assimilated and reduced to a number of organic compounds via the photosynthetic carbon reduction cycle1 and secondary biosynthetic pathways.2 Complete photosynthesis with isolated chloroplasts has for many years been a g...
متن کاملPhotosynthesis by isolated chloroplasts, simultaneous measurement of carbon assimilation and oxygen evolution.
Photosynthetic carbon assimilation by isolated chloroplasts and its associated oxygen evolution were measured simultaneously in a single simplified reaction mixture. Each showed an initial lag prior to the attainment of the maximal rate and the photosynthetic quotient was unity during the period of illumination. Following illumination an oxygen uptake was observed in the dark which was not acco...
