Activities and properties of phosphorylases of cytosol and mitochondrial fractions are studied in free-living turbellarias Phagocata sibirica and cestodes Bothriocephalus scorpii. The phosphorylase activities in P. sibirica and B. scorpii differ significantly both in form and in total activity of this enzyme. Dependence of the phosphorylase reaction rate on substrate concentration is studied. The high activity of phosphorylase as compared with that of hexokinase suggests glycogen to be the main energy source of the studied flatworms. Action of various effectors on activities of the cytosol and mitochondrial phosphorylases has been studied.
