Succinyl-CoA is converted to acetyl-CoA that is fed back into the cycle, with the net result of generating glyoxylate as the carbon fixation product, which is converted to pyruvate (Herter et al.
In C3 plants, respiration rates increase in the light, a process termed photorespiration, and this increased use of photosynthesis decreases the efficiency of carbon fixation.
However, leaf fall offsets this imbalance, although it also decreases carbon fixation, which may also be negatively impacted by the respiration of the disproportionate shoot wood accumulation.
With these low bacterial densities, the stoichiometric P requirement due to photosynthetic carbon fixation is higher than the P ingestion due to bacterial grazing.
