purpose of this lab was to study the specific characteristics of cations and anions‚ and ultimately to be able to identify an unknown substance based on our studies and tests using the logic trees developed through the experiment. A logic tree is a graphical display of the findings from this lab which‚ through a series of yes/no questions‚ elimination tests‚ will help us to identify and unknown sample. This lab will result in 2 logic trees‚ one for identifying cations and the other

In this lab 8 total substances were tested to find out whether they are a Protein or a Starch. It is my belief that only 1 or two of each of the substances in test 1( proteins) and test 2 (starch) will test positive for either protein or starch. For this lab the following materials were needed to complete the experiments in test 1 for proteins: Di water‚ ev milk‚ 50% egg solution‚ 1% sucrose‚ 4 test tubes‚ 1 test tube rate‚ safety glasses‚ pipets and the reagent solution. For test 2 for starches

The activity of an Enzyme is affected by its environmental conditions and changing these factors can alter the overall rate of the reaction. Reaction rates are influenced by external factors such as pH‚ temperature and salt concentration. Different enzymes have different optimum temperatures in which they are most efficient and different pH levels which is ideal for their formation of enzyme-substrate complexes. As the temperature increases‚ there is more movement of molecules and more random collisions

Daniel Bergey Lab 2: Proteins and Starches Purpose The purpose of lab 2 and both tests with proteins and starches is to determine which substance contains either protein or starch. Hypothesis Proteins: I predict that any substance I test that derives from a living organism is will test positive proteins. Any substance that isn’t from a living organism more than likely will test negative for proteins. Starches: I predict that any substance that contains any level of glucose will test positive

ENZYME LAB REPORT 1. In your own words‚ define objective qualitative and objective quantitative data. DO NOT USE EXAMPLES AS YOUR SOLE DEFINITION. (3) There are two different types of information that can be obtained from research. The types of information that can be obtained are quantitative and qualitative data. Research results are considered qualitative when the results can be answered with a simple statement of yes or no. Qualitative data does not attempt to give a numerical value; instead

Enzyme Immobilization Methods Covalent Binding: Covalent binding is a conventional method for immobilization; it can be achieved by direct attachment with the enzyme and the material through the covalent linkage [37]. The covalent linkage is strong and stable and the support material of enzymes includes polyacrylamide‚ porous glass‚ agarose and porous silica [38]. Covalent method of immobilization is mainly used when a reaction process does not require enzyme in the product‚ this is the criteria
