Influence of the Ionic Form of Copper (II) in the Aquatic Environment on the Contents of Metabolites of Glycolysis and Tricarbonic Acid Cycle in Carp Tissues

要約

The effects of copper ions at concentrations of 0.5 μg Cu2+ /L, 2 μg Cu2+ /L, 5 μg Cu2+ /L, and 10 μg Cu2+ /L on the processes of glycolysis and Krebs cycle in the liver, gills and muscles of carp were studied. At below-threshold concentrations of Cu2+ ions (0.5 μg /L) in the aquatic environment, the energy supply of adaptation processes in carp is performed mainly by the aerobic pathway. At their increased contents in water up to 2 μg Cu2+ /L, 5 μg Cu2+ /L, and 10 μg Cu2+ /L, aerobic processes are inhibited in fish tissues, while glycolytic processes are activated.
