摘要： The RQ breakpoint of carrot shreds occurred at about 1% O-2. At slightly below the RQ breakpoint, 0.5% O-2, glycolysis was affected. The low O-2 atmosphere caused a sharp increase in fructose 1,6-bisphosphate (Fru-1,6-P-2) and a slight decrease in fructose 6-phosphate (Fru-6-P), phosphoenolpyruvate, and pyruvate among the glycolytic intermediates. The low O-2 also caused an increase in fructose 2,6-bisphosphate (Fru-2,6-P-2) and ethanol. Fru-2,6-P-2 appeared to have promoted glycolysis, as noted by the increased activity of phosphate-dependent fructokinase. ATP level decreased under low O-2, but a sufficient level is thought to have been maintained for minimum metabolism by the increased glycolytic activity.
