on the activity of the purified enzyme was carried out by make the enzymatic reaction for 10 minutes at different temperature 25‚30‚35‚40‚45‚50‚60 and 70°C using an enzyme protein 0.1mg/reaction mixture and substrate concentration of 15 mg/reaction mixture‚ using a control of previously heated enzyme solution in the reaction. The data recorded in (table 27) and (figure 29) illustrate the effect of temperature of the reaction on the pectinase activity‚ it showed that the pectinase activity increased

In solving a crime‚ a crime scene is usually imperative to the investigation. Documenting a crime scene helps to establish some of the evidence or rather investigative leads which may help solve the case. Additionally‚ the leads found in the crime scene can help solve the case or determine what happened. Poor scene documentation can prompt unacceptable evidence in a courtroom‚ or missed evidence that may permit a victim to escape with a crime. Photography is important during the documentation of

Abstract The main goal of the enzyme kinetics experiment was to see how the phosphatase-catalyzed hydrolysis of p-nitrophenyl produced p-nitrophenol in the presence of phosphate and fluoride ion inhibitors of various concentrations. The calculated Km constant was found to be 0.22 for all reactions. The Vmax values for each inhibition ion were 0.00986 for the phosphate ion and 0.00436 for the fluoride ion. The inhibitor constant‚ Ki‚ was determined to be 0.0967 for the phosphate ion. The inhibitor

In this lab the peroxidase enzyme is tested in a dormant avocado seed as well as an avocado seed undergoing the process of germination. A gas pressure will be used to test the seeds and see if the peroxidase enzyme is present in either of the seeds. A catalyst is very similar to track spikes. Spikes increase a runner’s speed‚ as a catalyst speeds up the chemical reaction time in a plant. Neither the catalyst nor shoes are changed in these actions. Enzymes are macromolecules that act like catalysts

We have been studying cell division and cancer cells in class. At the beginning of the investigation‚ we knew how cells divided and symptoms for evidence of cancer. We also knew the process of cell reproduction as well as the cell cycle. My goal for this investigation was to use my knowledge to determine which patients if any had cancer. The guiding question was “Which Patients Could Have Cancer”. This question was related to the information we had been studying‚ because we had been studying cancer

Locard’s Exchange Principle and the use of Fingerprints: Edmond Locard (1877-1966) was a French scientist specialised in both medicine and law. Inspired by the work of Hans Gross‚ it was Edmond that created the concept that all objects of any material should leave traces of itself upon whatever it touches‚ even if it is the minutest amount‚ simply put as “Every Contact leaves a trace‚” Locard (1923). This is commonly known as Locard’s Exchange Principle. He believed that in circumstances such as

Arson investigation is a part of the more complicated science of fire investigations. The job of an arson investigator is to figure out if a fire has been intentionally set and how it started. I chose an arson investigator as a career is because my father has had over 25 years in this career and I am very interested in the career and it’s what I want to start pursuing after high school. You’re required to have a high school diploma or a G.E.D. and 5 years or more work experience in a related job

Unit 8 Essay Malcolm Johnson Fraud Investigation CJ125 Prof. Ayers 9/23/2012 Fraud Examination and auditing are very much related‚ but is not the same thing. Because most occupational frauds are financial crimes‚ there is necessarily a certain degree of auditing involved. A fraud examination involves a lot more than just a review of financial records. Other than a review of financial information a fraud investigation involves interviews‚ statement analysis‚ and also public record searches

Introduction Enzymes are key players in metabolism. A metabolism is the organic processes in a cell or an organism that are necessary for life. An enzyme affects the rate at which a reaction occurs when the activation energy is lowered. In this reaction the reactant is called the substrate which is that combine with enzymes molecules to form a temporary enzyme substrate complex. During this products are formed and the enzyme molecules released is unchanged. For the substrate complex to form the
