[Age-related and seasonal variations in the ATPase system of mitochondria of skeletal muscles in rabbit].
Seasoned variations in the activity of Mg++-ATPase and Mg++-DNP-ATPase have been revealed in studies on ATPase system of mitochondria of skeletal muscles of newborn, 7-, 10-day and adult rabbits. The degree of activation of ATPase by 2-4-DNP did not depend on the age of animals and the season of year. Absolute values for DHPATPhase were lower in young animals in spring. The activity of Mg++- and Mg++-DNP-ATPases and the extent of activation of the enzymes by Mg++ increased with the increase in the age of animals.
