新课程标准倡导探究性学习,强调生物学实验的操作技能、收集和处理信息的能力、以及交流与合作的能力等,探究酶的特性及活性受温度和酸碱度影响的实验是近年来高考的重点。比如,2004年上海卷考查了胰蛋白酶对底物的分解速度和温度之间的关系,2005年江苏卷考查了探究酶的高效性的实验,2006年广东卷考查了探究淀粉酶对淀粉和蔗糖的作用实验,2007年江 The new curriculum standards advocate inquiry learning, emphasizing the operational skills of biological experiments, the ability to collect and process information, and the ability of communication and cooperation, and so on, to explore the characteristics and activity of enzymes affected by temperature and pH is the focus of college entrance examination in recent years . For example, Shanghai Volume examines the relationship between trypsin decomposition rate of substrates and temperature in 2004, Jiangsu Volume examines the experiment to explore the efficiency of the enzyme. In 2006, Guangdong Volume examines the effect of amylase on starch and sucrose The role of experiment, 2007 Jiang
