- - Title: The amount and effects of an enzyme catalysis on hydrogen peroxide - Problem: To understand the properties of enzymes and how they can be affected by changes in temperature, pH, enzyme concentration, and substrate concentration. Also the relationship between the structure and function of enzymes, and the concept of initial reaction rates if enzymes. - Background: o Enzymes are proteins produced by living cells that act as a catalyst, which affect the rate of chemical reactions, in biochemical reactions. There are many elements of an enzyme- catalyzed reaction. The substrate in an enzyme- catalyzed reaction binds reversible to the active site of an enzyme. A result of this temporary union is a reduction of the activation energy required so that the products of the reaction are formed. Each enzyme is specific for a particular reaction because its amino acid sequence is unique and causes it to have a unique three-dimensional structure. The enzyme binds to the substrate by its active site.

    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.
