Experiment Data

From the first half of the graph, we can clearly discover the linear relationship be-tween enzyme concentration and the absorbance. Data suggest that as the concentra-tion of enzyme becomes greater, the relative absorbance increase proportionately. This result justified our assumption. However, the latter half illustrated a negative-related relationship. We suspected that we didn’t use enough substrate to allow the decomposition reaction. Also, we assumed that excessive concentration of enzymes will negatively affected the reaction rate.
