《探究影响酶活性的因素》是人教版高中新课标生物必修一《分子与细胞》第五章第一节中的第一课时。第五章《细胞的能量供应和利用》主要阐述的就是细胞的新陈代谢进行及其条件。其中,生物酶以其高效、专一的特性使得细胞内的新陈代谢反应能在常温、常压下快速有序地进行,这对于保障细胞正常生命活动具有极其重要的意义。但是,酶的催化活性是会受到环境中多种因素影响的。因此,让学生了 “To explore the factors that affect enzyme activity” is the first lesson of the first section of Chapter V of “Molecular and Cell”, New Curriculum Biology Compulsory for PEPC. The fifth chapter “the energy supply and utilization of cells” mainly elaborates on the cell metabolism and its conditions. Among them, the biological enzyme with its high efficiency and specificity makes the intracellular metabolism reaction can be carried out in a rapid and orderly manner under normal temperature and pressure, which is extremely important for guaranteeing the normal life activities of the cells. However, the catalytic activity of enzymes is influenced by many factors in the environment. So let the students out
