title: [Correlations of the individual levels of the activity and heat resistance of energy-support enzymes in the lake frog].
abstract: A study was made of the correlation between the levels of the activity and heat resistance of Na,K-ATPase, Mg-ATPase and succinate dehydrogenase (SDG) in Rana ridibunda. A correlation was observed between the activities of two ATPases, and between either of them and the activity of liver SDG. The correlation coefficient between the heat resistance levels was statistically significant only in SDG of liver and muscles. The question whether the criterion of T50% inactivation may be good for a comparative appraisal of the heat resistance of enzymes is under discussion.
