Enzymes Reactions to Changes in Substrate and Inhibitors Benjamin J. Mora Coronado University of Texas Rio Grande Valley at Edinburgh Abstract Purpose for the experiments was to test the enzymes in various scenarios and see how changing this would affect the rate of reaction. The enzyme source used in the experiments was Turnip Extract. Concentrations of Turnip extract for activity 1 where o.5ml‚ 1.0ml‚ and 2.0 ml as for the rest of the activities 2 Through 4 stayed at a consistent concentration

From this lab we can learn to observe physical properties of varying substances as well as to use chemical reactions to observe chemical observe the chemical properties of varying substances. In experiment #1‚ we were able to detect physical properties of the aluminum and copper sulfate simply by looking at the substances. We then combined the two substances to see if they would create a chemical reaction and test the chemical properties. After being combined‚ bubbles and gas were created and the

Andrea Negrete Abraham Lincoln High School Period 5 1/12/15 1/20/15 Partners: Nasya Aguilar LAB 1: Kinematic Equations and Reaction Time PURPOSE/QUESTION Apply kinematics equations for constant acceleration to find your reaction time. How much is it? How does reaction time change with practice? THEORETICAL The reaction time is the amount of time required to sense astimulus‚ analyze its meaning‚ and respond. Acceleration is the rate of change of velocity. Velocity is speed with direction

Title: Redox Reactions Research Question: Is it possible to determine if a redox reaction took place by using only the equation? Hypothesis: Yes‚ I believe it is possible to determine if this reaction took place by using the oxidation numbers in the equation. Variables: 1. I cleaned the reaction surface to limit contamination 2. I held the chemicals at approximately a 90 degree angle for consistency Introduction: Redox reactions occur when both oxidation and reduction take place. All atoms

anthracene from benzyltriphenylphosphonium chloride and 9-anthraldehyde through the reaction mechanism recognized as the Wittig Reaction. The Wittig Reaction allows the chemist to synthesize phosphoranes in the lab with relative ease. A more recent and inexpensive version of the reaction is the Wittig-Horner reaction (1). ABSTRACT Georg Wittig was a German chemist and Nobel Prize winner in 1979 for the Wittig reaction (1). He was born in Berlin‚ on June 16‚ 1897‚ and died August 26‚ 1987 (1). Wittig

Hardware Replacement Project IT/205 Randy Atkins December 16‚ 2012 Hardware Replacement Project The IT department wants to replace their old CRM with a new CRM solution. The only problem is that their existing hardware is old and out of date and will not support the new CRM. I was brought in to not only recognize the issue but to determine what equipment will be needed and help install the equipment. This needed to be done before the new CRM system can be installed and implemented. Before
