Question

Enzyme 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 pH on the rate of enzyme reactions Tube pH 1 2 3 4 5 3 5 7 9 11 Prediction no bubbles some bubbling strong bubbling very strong bubbling I T Observation no bubbles some bubbling strong bubbling very strong bubbling a What is the ideal pH for the enzyme catalase b What happens to enzyme activity when the pH is significantly higher or lower than the ideal pH c Relate what you ve observed to the activity of the enzyme salivary amylase Where is it formed Where is it active d Where is salivary amylase deactivated What causes it to be deactivated donaturization Again thinking of the effect of pH on enzyme
