Question

he Rate of an Enzyme Reaction These experiments will use the enzyme catalase which is found in potatoes Catalase acts on the substrate H O2 hydrogen peroxide to produce H O and O2 The O is released as bubbles Therefore the more bubbles you see the greater the reaction Base your responses on the following data table The effect of temperature on the rate of enzyme reactions Tube Pre Treatment Treatment Temp C Temp C C1 C2 C3 100 25 20 100 25 4 Prediction no bubbles some bubbling strong bubbling very strong bubbling Observations no bubbles some bubbling strong bubbling very strong bubbling a What is the preferred temperature for the enzyme catalase b What explains the level of activity with the catalase that was boiled prior to the experiment Relate this to protein structure and denaturization c What do you conclude about the effect of temperature on enzyme activity Don t just say that it has an effect say how it affects it d Based on your conclusion do you think you might digest ice cream at a slower or faster rate than a hot soup
