the enzymes were selected in such a manner , as to characterize most of the main metabolic pathways of energy supplying metabolism : hexokinase ( glucose phosphorylation , hk ) , glycerol-3-phosphate dehydrogenase ( glycerolphosphate metabolism or shunt , gpdh ) , triose phosphate dehydrogenase ( glycolytic carbohydrate breakdown , tpdh ) , lactate dehydrogenase ( lactate metabolism , ldh ) , citrate synthase ( tricarboxylic acid cycle , aerobic metabolism , cs ) , malate nad dehydrogenase ( tricarboxylic acid cycle , intra-extra mitochondrial hydrogen transport , mdh ) and 3-hydroxyacyl-coa-dehydrogenase ( fatty acid catabolism , hoadh ) .
