Abstract This lab was performed to determine the impact of temperature and pH on the efficiency of an enzyme. The results obtained, displayed the optimal pH and temperature for the tested enzyme as well as the flexibility of the enzyme around those optimal points.
Enzymes have an optimal pH at which the rate of reaction is highest As temperatures increase, the rate of reaction increases (higher kinetic energy = more collisions) At a certain optimum temperature, the rate of reaction will plateau (i.e. peak efficiency)
The purpose of this lab is to investigate the impact of temperature, substrate concentration, enzyme concentration, and the presence of an inhibitor on the effectiveness and rate of an enzyme. If the concentration of the enzyme or substrate is increased, the rate of the reaction will be increased as well.
Enzymes are protein molecules that speed up biological reactions. For digestion, it would be to speed up the rate of breaking down biomolecules, such as carbohydrates, proteins, and lipids.
Measure the effects of changes in temperature, pH, and enzyme concentration on reaction rates of an enzyme catalyzed reaction in a controlled experiment.
Investigate and describe the effect of changes in temperature and pH on enzyme activity. Investigate and describe the use of biological washing powders that contain enzymes. Extended: Explain enzyme action with reference to the active site, enzyme-substrate complex, substrate and product.
Students use a virtual simulation to explore properties of enzymes. They can adjust variables such as pH, temperature, and concetrations.
