Abstract
Many proteins act as catalysts which speed up or regulate a biochemical reaction. The kinetics of an enzyme can be investigated by measuring the reactants and products of the reaction over time. Research the enzymatic reaction of a protein and investigate its kinetics. Measure the production of hydrogen peroxide (H2O2) by catalase, the digestion of gelatin by papain, or any other enzymatic reaction you have access to. Once you have a method for measuring the kinetics of the reaction, conduct a series of experiments to measure the enzyme kinetics under different conditions. For example, you could systematically change the concentration of dissolved salts, or the temperature, or the pH of the solution in which you are measuring the enzyme kinetics. Or you could add an excess of one or more reactants, or an excess of one or more products to see what effect this would have on the enzyme kinetics.Variations

Career Focus
If you like this project, you might want to think about career opportunities in
Biotechnology.
Growing, aging, digesting—all of these are examples of chemical processes performed by living organisms. Biochemists study how these types of chemical actions happen in cells and tissues, and monitor what effects new substances, like food additives and medicines, have on living organisms.
