一、课堂实录这是一个高中生物必修第一册的实验六“探索淀粉酶对淀粉和蔗糖水解的作用”的实验课堂。实验的要点是,用淀粉酶分别催化淀粉和蔗糖的水解反应,再用斐林试剂鉴定溶液中有无还原糖,就可以看出淀粉酶是否只能催化特定的化学反应。经过老师的讲解,学生都能很成功地完成实 First, the class record This is a high school biology compulsory first six “to explore the amylase hydrolysis of starch and sucrose ” experimental class. The main point of the experiment is that using amylase to catalyze the hydrolysis reaction of starch and sucrose, respectively, and then using a Fehling reagent to identify the presence or absence of reducing sugars in the solution, it can be seen whether the amylase can only catalyze a specific chemical reaction. After the teacher’s explanation, the students can be very successful
