You are working with a specific enzyme-catalyzed reaction in the lab. You are a very careful experimentalist, and as a result, at the beginning of each of your experiments, you measure the temperature in the lab. On days 1 through 5, the temperature in the lab was 20oC. Today is day 6 of your experiment, and the temperature in the lab is 30oC. How do you predict that this will alter the rate of your enzyme-catalyzed reaction?
A. It will decrease the rate B. It will increase the rate C. It could possibly increase or decrease the rate D. it will not affect the rate Clarify Question What is the key concept addressed by the question? Gather Content What do you already know about enzyme rates and temperature? What other information is related to the question? Choose Answer Do you have all necessary information to make a judgment? Reflect on Process Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
