What is the independent variable in this test? The temperature of the liver 2. What is the dependent variable in this test? Reaction rate 3. What is the optimal temperature for catalase (biggest reaction)? Freezing 4. Why did reactions not proceed as quickly at the other temperatures? The enzyme got denatured When it gets cold, the enzyme does not react as quickly Part 2: Please click here for the link to the lab. Overview: In this investigation, you will determine the effects of substrate concentration and pH on the rate of an enzyme-catalzyed reation.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
