Abstract:
The effect of various sugar phosphates on CO(2) fixation in Anabaena flos-aquae was investigated and found to be very similar to that found for isolated spinach chloroplasts. One exception, glucose 6-phosphate, has a stimulatory effect on CO(2) fixation in Anabaena but not in isolated chloroplasts.Further examination of the role of glucose 6-phosphate metabolism in Anabaena indicates that: (a) this sugar phosphate can be taken up; (b) its uptake is greater in the light than the dark; (c) turnover of glucose 6-phosphate is inhibited in the light; and (d) glucose 6-phosphate can support dark CO(2) fixation. These results are discussed with reference to photosynthesis-related control of glucose 6-phosphate metabolism and the role of glucose 6-phosphate as a source for reducing equivalents and ATP in blue-green algae.

Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
