Popis:	The heat production accompanying interaction between bundles of glycerinized fibers of rat striated muscles and ATP was measured. Interaction both of relaxed and of initially contracted bundles was investigated. The kinetic temperature curves show that during interaction between ATP and the uncontracted bundle a peak of thermal power is observed to coincide with the contraction process, whereas previously contracted fibers give no such effect. It is concluded that the level of ATPase activity is directly dependent on the conformation of the actomyosin system.
