Investigation: Apples and Pectinase Enzyme
In this experiment, high school students will investigate the role of enzymes by testing the effects of pectinase on apples. The objective is to compare the amount of juice extracted from apples treated with pectinase to those left untreated. In addition, students change the temperature of the solutions to compare enzyme activity at cold and…
