LABORATORY REPORT Activity: Enzyme Activity Name: Angela Collins Instructor: Catherine Rice Date: 07.09.2014 Predictions Sucrase will have the greatest activity at pH 5 Sucrase will have the greatest activity at 70 °C (158 °F) Sucrase activity increases with increasing sucrose concentration Materials and Methods Effect of pH on Enzyme Activity Dependent Variable amount of product (glucose and fructose) produced Independent Variable pH Controlled Variables temperature, amount of substrate (sucrose) present, sucrase + sucrose incubation time Effect of Temperature on Enzyme Activity Dependent Variable amount of product (glucose and fructose) produced Independent Variable temperature Controlled Variables pH, amount…show more content…
ith the myosin have been activated by the ATP, they will bind the action binding site. 2. Salivary amylase, an enzyme in saliva that breaks down starch, has an optimal pH of 6.7-7.0. Explain why salivary amylase is active in the mouth, but becomes inactive in the stomach. the stomach has a gastric juice which contain HCI. once its denatures it cant break down anymore glucose or starch it is then deactivated.
