摘要
应用酶学分析法测定了越冬后北草蜥胃、肠组织中蛋白酶、淀粉酶、纤维素酶的活力。结果表明 ,不同年龄、性别的北草蜥同一组织中消化酶活力有显著差异 ;不同地理种群的北草蜥同一组织中消化酶活力有显著差异 ;不同消化酶在北草蜥同一组织中的活力有显著差异 ;在北草蜥不同的组织中同一消化酶的活力有显著差异。说明北草蜥消化酶的活力与年龄、性别、部位和地理环境等因素有关 ,受食物组成、能量需求和遗传等因素的影响 ,产生了不同的酶活力和分布。这也说明生物长期适应环境 。
The activities of pepsin enzyme amylase and cellulase from stomaches and intestinesof post hibernation Takydromus septentrionalis were analyzed with the enzyme analytical method.Results showed that the activities of the same digestive enzyme in the same organ of different ages and sexes were significantly different.The activities of the same digestive enzyme of the same organ were notablely different in different geographical Populations.The activities of digestive enzyme of the same organ were strikingly different.The activities of the same digestive enzymewere markedly different in different organs.It is concluded that the differences of the digestive enzyme activity were determined by heredity and the living environment.
