as the histological degree of malignancy increases and the level of differentiation of the mammary cancer decreases , the activity of glycolysis and pentous shunt enzymes , lactate dehydrogenase and glucose-6-phosphate dehydrogenase , increases and that of the krebs cycle enzymes , succinate and malate dehydrogenase , as well as the enzyme of glycerophosphate shuttle mechanism and oxidation of glycerol-l-glycerophosphate dehydrogenase decreases simultaneously .
