[Changes in the activity of various enzymes of carbohydrate metabolism in the liver and skeletal muscles of pigs during ontogenesis].
Hexokinase, glucokinase, phosphofructokinase, glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase activity was studied in the liver and musculus quadriceps femoris of 110-day foetuses 1, 2, 3, 30 and 60-day piglets and in adult pigs. The activity of all enzymes in the tissues of newborn piglets is considerably higher than in the tissues of foetuses. The activity of hexokinase in both tissues of piglets increases in the first days after birth and lowers by the one month age. The phosphofructokinase activity in the skeletal muscles and the glucokinase one in the pig liver increase during the postnatal development. The activity of glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase in both tissues of pigs increases after birth and then decreases. Glucose metabolism in the pig liver at all stages of odontogenesis proceeds more intensively by the pentose phosphate pathway, and in the skeletal muscles--by glycolytic one.
