Quezon City 1101 Philippines ABSTRACT The rationale of the experiment is basically founded in the concept of reaction rates as affected by enzyme‚ and how the enzyme works is competed by a competitive inhibitor‚ thereby impeding the forward reaction. In this experiment‚ o-diphenol oxidase‚ an enzyme that causes the browning in fruits‚ was extracted from banana and reaction rate of this was established with various concentrations of catechol‚ the substrate‚ using the Michaelis-Menten‚ Lineweaver-Burk

There are reactions that build up molecules‚ | |synthesis/anabolic reactions‚ as well as reactions that break down molecules‚ catabolic reactions. Together the sum of all anabolic and | |catabolic reactions in our bodies makes up our metabolism.

Temperature and enzyme activity Aim: To determine the effect of which the temperature of the enzyme has on the rate of the enzyme catalysed reaction. Hypothesis: The rate of reaction of an enzyme catalysed reaction will increase as the temperature of the enzyme approaches the optimum temperature. Surpassing the optimum temperature will result in a drop in enzyme activity. Materials: 6% hydrogen peroxide Liver suspension 10 test tubes 4 beakers Thermometers Measuring cylinders Test

Chemical reactions are at the heart of all biological processes. The body must regulate precisely all the chemical reactions going on in order to maintain life. Much of this regulation is done by changing the activity of enzymes.(www.biology.kenyon.edu) Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells.(www.livescience.com) Enzymes speed up chemical reactions by providing an alternate

for understanding the relationship of structure to stability and reactivity. Reactions are usefully described in terms of potential energy diagrams such as shown in Figure 3.1‚ which identify the potential energy changes associated with the reacting molecules as they proceed to products. The diagram plots the free energy of the system as a function of the progress of the reaction. For each individual step in the reaction there is a transition state representing the highest energy arrangement of the
