[Hexokinases and glycolysis in embryonic and denervated rat liver].
Certain similarity in the isoenzymic composition of hexokinase (HK) and the rate of glycolysis in embryonic and denervated liver of rats has been revealed. These tissues exhibit high activity of HK-II and especially HK-III, which has the highest affinity to glucose. Depending on the isoenzymic composition of HK, the rate of glycolysis in embryonic and denervated liver is rather intensive even at low external concentrations of glucose and is not significantly affected by the increase in the level of the latter. It is suggested that the observed similarity results from a reduced activity of the sympathetic nervous system. This conclusion is confirmed by low catecholamine content in the tissues studied.
