Abstract Over a two week period of time in the laboratory‚ we experimented and tested the reaction rate of a peroxidase enzyme and the factors that affected it‚ both positively and negatively. The purpose of these experiments was to probe and manipulate the activity of the enzyme peroxidase by varying temperature‚ pH‚ the amount of enzyme compared to the substrate and the effect of hydroxylamine. Peroxidase activity is expressed when the potato extract is subjected to stresses such as low temperature

Experiment 2: Intermolecular Forces Performed: 9/12/2011 Submitted: 9/20/2011 Chemistry 1046L PART I: Purpose: The purpose of partI in this experiment is to identify a variety of unknown substances’ properties using observations of the temperature changes that occur during evaporation. We know that substances with weaker intermolecular forces‚ such as London dispersion‚ will have a faster vaporization rate and thus a higher temperature difference compared to

found its way into discussion through several media outlets‚ including medical journals‚ film and literature. Questions of who we are as both individuals and as a human species are raised in hopes of addressing the controversial dilemma surrounding this biological manipulation. Several films and novels have wrestled with the issue through the narration of fictional characters who find themselves in the eye of the storm‚ as the products of genetic cloning. “Never Let Me Go” by Kazuo Ishiguro addresses
