...B. Pelster; J. Hicks; W. R. Driedzic ABSTRACT The contribution of the pentose phosphate shunt to glucose metabolism in the swimbladder tissue of the American eel Anguilla rostrata has been evaluated by comparing the rate of 14 CO 2 and [ 14 C]lactate production from [1- 14 C]glucose and [6- 14 C...

..., only about 1 % of the glucose was oxidized, while about 80% was fermented to lactic acid. The remaining 0.14 μmolmin −1 glucose was presumably catabolized through the pentose phosphate shunt, as indicated by the CO 2 production of 0.16 μ molmin −1 that cannot be explained by aerobic metabolism. 09...

... mirabile, the liver and white skeletal muscle to evaluate whether the pentose phosphate shunt may contribute to glucose metabolism in the swimbladder tissue. The activities of enzymes of the pentose phosphate shunt were higher in the swimbladder epithelium than in white muscle, and close to those...

... lactate concentrations (20mmol l −1 ). The observed K m values and competitive interactions suggest that changes in plasma concentrations associated with environmental stresses can considerably alter the relative rates of oxidation of glucose and lactate in vivo . Considerable pentose-phosphate shunt...
