Before choosing a specific aspect to study, all the lab groups did a general experiment to study the reaction rates of a specific enzyme, catecholase. Catecholase is an enzyme found in some many fruits and vegetables, and is responsible for the browning that occurs when a fruit is cut or damaged. Its substrate, catechol, reacts with oxygen in the air to produce water and benzoquinone. This is what has the reddish brown color.
