Effects of pH on Amylase Activity

Abstract: Amylase is an important enzyme in the human body as it allows for the consumption of starch by breaking the polysaccharide down into maltose units. All enzymes, including amylase, function best at a certain optimal pH. Therefore, in this experiment, the effect of different pHs on the reaction rate of amylase is studied. It was hypothesized that the amylase-starch reaction would proceed fastest at a pH closest to that of the body, or 7.0, since that is where the enzyme normally functions. Lower and higher pHs would cause the enzyme reaction to proceed slower. In order to test the hypotheses, several reactions of amylase and starch solutions with varying pHs were set up. The addition of the mixture to…
