Therefore‚ it will be presumed that the result of this experiment by isolating the polyphenol oxidase within the potato extract through the oxidation of 5mM dopa solution with highly concentrated enzymatic preparation of polyphenol oxidase with a buffer as the diluent will indicate a rapid increase in the rate of the reaction as well as the amount of activity present in the potato extract. Proposing that Vmax is proportional to enzyme concentration‚ a linear relationship should be present and enzymatic

Imperata cylindrica as an Antibacterial Agent for Escherichia coli INTRODUCTION a. Background of the Study We all know that bacteria are everywhere. Bacteria are microscopic organisms whose single cells have neither a membrane-enclosed nucleus nor other membrane-enclosed organelles like mitochondria and chloroplasts. One example of bacteria is E .coli is a bacterium that is commonly found in the gut endotherms. E. coli and related bacteria constitute about 0.1% of gut flora‚ and fecal-oral

crystallization- The purpose of this lab was to extract and crystallize compounds in a mixture using acids and bases. 1 gram of the unknown was dissolved into 30 mL of ethyl acetate. The mixture was then transferred to a separatory funnel. Using aqueous solutions of different pH we were able to separate organic acids‚ bases and neutral compounds from each other. Using three 10 mL portions of HCl‚ we reacted the HCl with the base in solution. This made it possible to extract the base from the mixture. Organic
