    Just as in science‚ a catalyst speeds up the rate of the chemical reaction; in literature‚ a catalyst is a person‚ idea or event that initiates and develops the conflict of the story. In "A View from the Bridge" and "The Glass Menagerie"‚ the catalysts used are introduced at different points in the plays and play different roles. In " A View from the Bridge"‚ Rodolpho‚ the catalyst‚ is introduced in the exposition‚ and plays a major role in the play. He initiates the conflict by being attracted

    correlation between catalase concentration and the rate of reaction. This occurs because as the enzyme concentration increases‚ there are more enzymes available to catalyze substrates. More enzymes means more reactions can take place at a time‚ thus a faster rate of reaction. Overall‚ based on the results of table 2.0 and graph 2.0‚ it is prevalent that there is a positive correlation between the concentration of enzymes and the rate of

    Received July 18‚ 1997X A radiochemical enzyme assay for studying cyclooxygenase (COX)-catalyzed prostaglandin biosynthesis in vitro was optimized with respect to both COX-1 and COX-2 activity. The assay can be used to assess the relative selectivity of plant-derived inhibitors on COX-1 and COX-2. Assay conditions were optimized for both enzymes with respect to concentration of cofactors (l-epinephrine‚ reduced glutathione‚ and hematin)‚ activation time (enzyme and cofactors)‚ reaction time‚ and

    The Effect of Temperature on the Enzyme Catalase Stephen Francis Biology 183 Abstract This experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at room temperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this experiment proved

    Biology Enzymes IA Design Introduction: Enzymes are globular proteins‚ they are responsible for most of the chemical activities of a living organism. They act as catalysts‚ substances that affects the reaction of other substances without being destroyed or altered during the process. They are extremely efficient in the body system of living organisms‚ one enzyme may catalyse over a thousand chemical reactions every second. But there are certain conditions that need to be fulfilled in order for the
