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.
在对新生、7日龄、10日龄和成年兔骨骼肌线粒体ATP酶系统的研究中，已揭示出Mg++-ATP酶和Mg++-DNP-ATP酶活性的季节性变化。2-4-DNP对ATP酶的激活程度不依赖于动物年龄和年份季节。春季幼龄动物的二磷酸己糖磷酸酶（DHPATPhase）绝对值较低。Mg++-ATP酶和Mg++-DNP-ATP酶的活性以及Mg++对这些酶的激活程度随动物年龄增加而升高。
