Sample Lab Report: Factors which Affect the Activity of the Enzyme Catalase Purpose: Must include: background information about concepts involved in the lab‚ statement of purpose of the lab identification of independent and dependent variables. A hypothesis is often not necessary or appropriate. Enzymes are proteins that speed up chemical reactions in cells. They break down molecules called substrates. Each enzyme has only one substrate that it breaks down. Enzymes are produced in

NT1210 Chapter 4 Lab 4.1.1 Standards are put in place to make everything work together error free. Because Stability‚ Consistency‚ Minimization of packet errors. 4.1.2 Because the voltage used to transmit data needs only be high enough for the receiver to detect it. Making the voltage higher would make the receiver electronics more difficult. 4.1.3 Hospitals‚ security systems‚ PA & recording studios. The drawback of STP cables is that they will increase the total cost of an installation.

Period 1 10/14/12 Enzyme lab Enzymes are biological catalysts that speed up the process of chemical reactions. They are also proteins‚ and most enzymes activities occur within organism. They decrease activation energy‚ energy that is needed to start a chemical reaction. Enzymes are substrate specific substrates ending in "-ase"‚ enzymes ending in "-ase". External factors‚ such as temperature‚ pH‚ and concentration of the substrate‚ affect the enzymes activity in the lab‚ pectase and cellulase will

phthalate‚ solution and the second one is determining the molarity and percentage by mass of the acetic acid in vinegar. 6 g of NaOH solid is used to dilute with distilled water to prepare a 250 mL of 0.6M sodium hydroxide. pH electrode will be immersed into the solution and a grph of pH versus NaOH is obtained. The next part is to determine the molarity of acetic acid and mass percent in vinegar where the vinegar is diluted as the same way in previous part. The titration is repeated twice for both parts

conditions affect the rate at which enzymes accelerate/cause reactions In this lab students measured the height of the foam after catalysis between catalase (enzyme) and 7 other (solutions) to determine which solution had the fastest reaction rate.. The control variable of the experiment would be the solution of only hydrogen peroxide‚ water‚ and catalase. The independent variables of the experiment were the abiotic factors such as PH level‚ temperature‚ and the amount of salt within the environment. The

Introduction Background The purpose of this lab was to understand animal response to stimuli which is also called taxes or taxic. Brine shrimp were the organisms that we observed during this lab and we observed how they responded to thermotaxis‚ phototaxis‚ and chemotaxis. Brine shrimps are also known as Artemia saline. They are commercially used for fish food and they are found worldwide in high salinity waters (Leady‚ 2015). Question What environments do brine shrimp prefer? Hypothesis
