... ), rainbow trout ( Oncorhynchus mykiss ), lumpfish ( Cyclopterus lumpus ) and short-horned sculpin ( Myoxocephalus scorpius ) under normoxic and hypoxic conditions. These species had plasma glucose levels of 5.1, 4.8, 0.9 and 0.5 mmol l −1 , respectively. Rates of glucose metabolism and lactate production...

... utilization assessed by both simple chemical analysis of glucose disappearance from the medium and 3 H 2 O production was half the rate of lactate production and as such extracellular glucose was not available for oxidative metabolism. Overall, extracellular glucose makes only a minor contribution to ATP...

... from anaerobic metabolism. During hypoxia, a metabolic depression of approximately 2/3 occurred for non-contractile processes in both turtle and trout preparations. During hypoxia, lactate production and residual oxygen consumption were similar in turtle and trout. Cellular energy state...

... – exchange lactate production oxygen consumption. The goldfish hepatocyte has a remarkable degree of anoxia-tolerance, which is largely based on its ability to downregulate ATP production and ATP consumption coordinatedly during energy limiting conditions ( Krumschnabel et al., 2000 ). This general...

... microcalorimetry), lactate production, ethanol production and the maintenance of ATP, ADP and AMP levels and energy charge were measured in telencephalic brain slices during anoxia. In response to anoxia, heat output decreased by 37 %, corresponding to a 31 % fall in ATP turnover rate. Adenylate phosphates...

... lactate production. Our data therefore show that white cells account for almost half of the energy turnover in trout blood. Adrenergic stimulation elicited a significant increase in total as well as ouabain-sensitive (a Na + /K + -ATPase inhibitor) red cell oxygen consumption. However, the ouabain...
