①酶在强酸、强碱和高温条件下变性失活

②酶都是在细胞内的核糖体上合成，在细胞外或细胞内起催化作用的物质

③“ATP ADP+Pi+能量”，整个反应是一个动态平衡的过程

④自然界中的光能、热能、机械能、电能和化学能都可以转化为细胞中的ATP

⑤一个ATP分子彻底水解需要消耗4个水分子

⑥人的心肌细胞中，ATP合成速度远远大于分解速度，从而保证心肌细胞有充足能量．

近代化也叫现代化，其主要表现为经济领域的工业化，政治领域的民主化和法制化，思想文化领域的理性化和科学化等，实现近（现）代化是近代以来世界各国发展的必由之路。

    We call the Chinese New Year the Spring Festival. There is a name for each Chinese year. We may call it the year of the Dog, the year of the Monkey or the year of the Pig, etc. And this year is the year of the Snake.

    Before New Year's Day, people are busy shopping and cleaning their houses. On New Year's Eve, there is a big family dinner. After dinner all the family stay up late to welcome the New Year. On the first day of the New Year, people put on their new clothes and go to visit their friends and relatives. They say “Good luck” and some other greetings (问候) to each other. People usually have a very good time during the festival.
