Uninhibited enzyme enzyme + inhibitor Substrate Concentration The graph above measures the rate of enzyme activity as the concentration of substrate is increased in the presence of a "normal" enzyme and after an inhibitor has been added to the enzyme. What type of inhibitor does this represent? Oa. irreversible Ob. competitive Oc. noncompetitive O d. all of the above Enzyme Activity

help with question 5 please
What chemical reaction is being catalyzed in this experiment? Label the substrate(s), enzyme and product(s). Based on the information in the data table and your graph, is there an optimum temperature for catalase that makes it the most productive in terms of reaction rate? If so, what is the temperature? 3. At what temperature, does the rate of the reaction decrease? Explain why.
What is the impact on reaction rate when you increase the amount of substrate (reactant) in an enzyme mediated reaction? What happens when you increase the amount of enzyme?
