Brooke Strowd AP Biology Ms. Butler 28 January 2013 I. Title: Effect of a Catalyst on Reaction Rate II. Introduction: The basis of the experiment is the enzyme; an enzyme is a biological molecule that acts as a highly selective catalyst. By combining with a substrate‚ an enzyme is able to create a new product that helps the body function. (Ex. Lactose/Lactase) A substrate is a molecule an enzyme acts upon‚ the two combine at an area called an active site. This active site allows induced fit

The Columbian Exposition was meant to celebrate the arrival of Christopher Columbus in 1492. Not only did the festival commemorate the arrival‚ but it was symbolic with the realization and development made of the Americas from 1492. The festival was held years after the Chicago fire and the American civil war‚ which was an indication that then festival served to remind the natives of the progress achieved from 1492‚ which were similar to those of the reconstruction era (Galvin). The Columbian Exposition

Effects of SO2 On Fermentation Rates Purpose SO2 is the primary inhibitor for natural microbiological growth in wine. It prevents the browning of juice by inhibiting phenol oxidase activity and kills the natural yeast cells for the utilization of fermentation-controlled commercial Saccharomyce strands (Boulton et al. 1996). SO2 is pH and temperature dependent and can exist as several forms. The bisulfate form (HSO3-) can complex with soluble solids such as anthocyanins and acetaldehydes to become

Part I: Briefly evaluate how Google’s Prediction Markets have worked to date. To what extent have the markets been successful or unsuccessful? 250 When the five Googlers got together to start with this project‚ their main objective was to launch an internal prediction market and test if crowds would make more accurate predictions than individuals’. To determine if this project was a success or not we need to determine our parameters of success. Moreover‚ we also think that the success will be
