酶是由生物体产生的具有催化活性的催化剂。它具有催化效率高,专一性强等特点。我们在有机化学教学中进行了如下有关酶催化的演示实验。一、过氧化氢酶催化双氧水分解在动物组织中,如肝、肾及血液中均含有过氧化氢酶,过氧化氢酶仅分解过氧化氢,并具有一般化学催化剂所难以比拟的催化效率,每分子过氧化氢酶,在一分钟内能促使大约五百万个过氧化氢分子分解。通过下面演示,可
Enzymes are catalytically active catalysts produced by organisms. It has high catalytic efficiency, specificity and so on. We conducted the following demonstration experiments on enzyme catalysis in organic chemistry teaching. First, the catalase catalyzes the decomposition of hydrogen peroxide in animal tissues, such as liver, kidney and blood are catalases, catalases only decomposition of hydrogen peroxide, and with the general chemical catalyst is difficult to compare the catalytic efficiency, Per molecule of catalase, in a minute can promote about five million molecules of hydrogen peroxide decomposition. Through the demo below,
