13. In the graph you created in the lab simulation with your data:a.What is represented by the green line?With the green line the number of molecules of the product formed in a minute greatly increased once more substrate was added. With PH7 it represents this datab.what is the optimal pH for lactase enzyme activity?ANSWER: Ph714. Consider only the experiment you conducted with 0.5 g. of lactose.a.What is the independent variable? ANSWER: The Amount of Lactose
b.What is the dependent variable? ANSWER: The amount of lactose substance14. The maximum rate of this reaction is 350 molecules product/minute. List two changes you could make in the experimental conditions or variables that would increase this reaction rate. Explain why each change you listed will increase the reaction rate.I would add more lactose in the tubes which would have given a higher reaction time, because the substance would react faster and have a higher molecule product/minute.
