the results of the conducted analysis indicate a heterogenic distribution of the creatinephosphokinase isoenzymes within the cells : about 30 % of the cellular activity of the enzyme is contained in the mitochondria ( the mitochondrial isoenzyme ) 50 % is comprised by the fraction dissolved in the cytoplasm ( isoenzymes mm , mb and bb ) , and about 20 % -- in the myofibrils ( isoenzyme mm ) , 5 % of them being extracted only by a 0.9 m kcl solution .
