Enzymes are a type of specialized protein. One part that makes the enzyme so special is that it has what is known as an active site, where another molecule or substrate can bind. This allows an enzyme to act as a catalyst to start a biochemical reaction. In the experiment I will use an enzyme in yeast called catalase to start a biochemical reaction. The catalase will work as a catalyst to convert hydrogen peroxide to oxygen and water. I will specifically be asking how PH or acid levels effect enzyme activity. In previous experiments it was already concluded that enzyme activity peaks at a certain temperature. I believe that at a certain PH level Enzyme activity will also peak. If the PH is lower (more acidic) then the enzyme reaction will be lower causing less inflation of the balloon. I will need the following materials for this experiment; pH paper •hydrogen peroxide solution •plastic beakers or cups •vinegar •yeast (can be purchased at grocery store if more is needed) •balloons •plastic bottle •marker for labeling of beakers •Cell phone/digital camera - pictures required

    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.
