细胞中几乎所有的化学反应都是由酶催化的,酶是由生物活细胞产生的一种具有催化活性的有机物,酶对化学反应的催化效率被称为酶活性。细胞都生活在一定的环境中,环境条件会影响细胞内酶的活性。从而使酶的活性发生改变。本实验旨在探究不同p H对酶活性的影响,通过学生自己设计实验,最后得出强酸强碱会破坏酶的结构,使酶失活。 Almost all chemical reactions in cells are catalyzed by enzymes, a catalytically active organism produced by living cells. The catalytic efficiency of an enzyme in a chemical reaction is called enzymatic activity. Cells are living in a certain environment, environmental conditions will affect the activity of intracellular enzymes. So that the enzyme activity changes. The purpose of this experiment was to investigate the effect of different p H on enzyme activity. By designing experiments by students themselves, it was concluded that the strong acid and alkali would destroy the structure of enzyme and inactivate the enzyme.
