the object of this work was to study the activity and the isozyme spectra of hexokinase ( the triggering enzyme of glycolysis ) , glucose-6-phosphate dehydrogenase ( the key enzyme of the pentose-phosphate shunt ) , malate dehydrogenase and isocitrate dehydrogenase ( the enzymes of the citric acid cycle ) and alcohol dehydrogenase ( the enzyme involved in the first steps of ethanol oxidation ) in saccharomyces cerevisiae , race ya , s. carlsbergensis , race 4228 , and their hybrid 67 .
