生物体内时刻都在进行着旺盛的新陈代谢活动,这些化学反应之所以能顺利地进行,是因为在酶的催化作用下完成的.酶涉及到生物体内几乎所有的生化反应,也是高考常考的考点,尤其是与酶有关的实验设计,现就此做一分析.一、与酶有关的实验设计思路1.酶的本质(1)原理:绝大多数的酶是蛋白质,少数酶是RNA,要探究或验证高中阶段的某种酶是否为蛋白质,可运用对照实验的方法用双缩脲试剂进行.当然
The life of the body are in the process of exuberant metabolic activity, the reason why these chemical reactions can be smoothly carried out, because the enzyme catalyzed by the enzyme involved in almost all biochemical reactions, but also the college entrance examination often test points , Especially with the experimental design of the enzyme, to do an analysis of this.First, the experimental design ideas related to the enzyme 1. The nature of the enzyme (1) Principle: The vast majority of enzymes are proteins, a small number of enzymes are RNA, to explore Or to verify whether a high school enzyme is a protein, the control experiment can be used biuret reagent .Of course
