Assignment 1: Discussion Assignment Discussion Question 1 What is the difference between biochemical reactions in healthcare? Biochemical reactions occur as a chemical reaction, which naturally takes place in a living organism. It happens within a cell involving a catabolic reaction (breaking down of molecules) or a anabolic reaction (building up of molecules). The process involves a diversity of biomolecules interacting with one another in order to make up a new biochemical for a particular…

The Effects of Substrate Concentration and Temperature on a Catalase Reaction Rate Introduction Catalase is a vital component in the human body. The most crucial of which would be Enzymes, these are protein catalysts. A catalyst speeds up a chemical reaction rate. Virtually all chemical reactions within the human body require a catalase enzyme to be completed in the proper amount of time. The decomposition of hydrogen peroxide to oxygen and water can be completed with the catalase enzyme…

rate of reaction? Problem: What effects does temperature have on the rate of reaction? Purpose: The aim of this investigation is to investigate how changing the temperature of sodium thiosulphate affects the rate of reaction in a chemical reaction. In order to complete this practical the temperature will be changed three times and the rate of reaction will be measured each time. Variables: Independent: -the temperature of the sodium thiosulphate. Dependent: -the rate of reaction.…

Discussion In this experiment, the chemical reaction between acetone (CH3COCH3) and iodine (I2) to make CH3COCH2I, I-, and H+ was observed. Under normal circumstances, this reaction would occur very slowly. In order to speed up the process, hydrochloric acid (H+) was used as a catalyst. A catalyst is a substance that can speed up a reaction by lowering the activation energy of the reaction. It does this by changing the mechanism of the reaction and providing more energetically favorable…

“Classifying Chemical Reactions - Lab Report” I - Introduction - Chemistry is the study of the composition, structure, properties and change of matter. In chemistry, chemical and physical changes are used to help scientists understand how different substances react given various circumstances. A chemical change is any change resulting in the formation of a new chemical substance(s). A physical property is any change that does not involve the chemical makeup of a substance at all. In total…

In an enzyme catalyzed reaction, it is important that we have an enzyme, a substrate, and a product. Alkaline Phosphatase, the enzyme in our experiment, is an enzyme protein found in all body tissues especially the liver, intestines, and bone (U.S. National Library of Medicine). In order for body processes to carry on in a normal and efficient way, it is critical that this enzyme is present in the system of living things. Alkaline Phosphatase is important for the development of teeth and bones…

economy, the human body, and the environment, copper has been studied and manipulated to explore its uses and properties. In the experiment performed, the copper cycle was observed by placing copper through a series of chemical reactions to demonstrate the different reaction types. Materials and Methods To begin the experiment, a 50 mL beaker was placed on a hot plate with a ring stand along with a fume hood made out of a funnel, rubber tubing, and an aspirator. Before advancing through the…

Polymerase chain reaction (PCR) Generalities PCR is a method developed in 1985 by Kary Mullis and to obtain, by coupling a heat-resistant DNA polymerase and without cloning, amplification of a fragment of DNA known. Initially, DNA polymerase was isolated from a bacterium thermophilne (resistant to significant increases in temperature), as Thermus aquaticus (Taq polymerase). Currently, we use recombinant enzymes, whose; elaboration is easier and greater efficiency. The general principle of PCR is…

A Friedal-Craft reaction was performed to synthesize 1,4-di-t-butyl-2,5-dimethoxy-benzene from p-dimethoxybenzene and t-butyl alcohol. The product of the reaction was filtered using a Hirsch funnel, before recrystallizing and filtering a second time. The recorded mass of the product was .08g and the melting point was 47-52.7 °C. Introduction1 This experiment was designed to practice working with electrophilic aromatic substitution reactions. Specifically, a Friedel-Craft reaction was used to…

Experiment 5: Anions and Redox Reactions Introduction (a) Objectives General: To examine the importance of potassium permanganate as an oxidising agent and the strong powers of halogens in oxidation. Part 1 Determining the colour associated with a certain halogen by adding a sample of the halogen to cyclohexane and recording the colours observed. Part 2 Identifying a halogen referring to the colours recorded in part 1, by reacting the halogen with a halide and observing the colour present.…
