Hexokinase (HK) (a) and succinate dehydrogenase (SDH) (b) enzymatic activity. HK activity was measured in lysates and SDH activity was measured in mitochondrial lysates of cells cultivated in rich (R) and poor (P) media in aerobic (+) and hypoxic (-) conditions for 72 h only (HK) and for 24 and 72 h (SDH). Specific activity U was calculated as the amount of substrates converted by 1 μmol of enzyme per min. Single activities are represented by the average number from two biological replicates, each tested in three technical replicates, bars are standard deviations
