Name: Edreih Aldana Lab: Lab #9, Enzymes, Effects of Substrate Concentration on Catalase Activity Due Date: 10/23/15 Purpose The main purpose of this experiment was to learn about the effects of substrate concentration on catalase activity. Introduction Enzymes are protein molecules that act as catalysts and speed up many different chemical reactions in cells. To speed up, or catalyze, a chemical reaction the enzyme must bind with a substrate on the enzyme’s active site (Brooker, 2014). Under ideal circumstances, an enzyme will react at its maximum efficiency and chemical reactions will happen very quickly. There are many factors that can affect an enzyme’s activity and reaction rate that affect its efficiency (Castro, 2014). Some factors that affect an enzyme’s activity are temperature, pH, inhibitors, enzyme concentration, and substrate concentration. The effect of substrate concentration is the variable that was studied in this lab report. The enzyme used in this experiment was called catalase and it was isolated from potato cells. Its substrate is hydrogen peroxide, and its products are oxygen gas and water. In this experiment, the behavior of the enzyme catalase was tested at a variety of different substrate concentration levels. The

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
