To conduct your laboratory exercises, use the Laboratory Manual that is available in the “Content” section of the Leo classroom or at the eScience Labs Student Portal. Laboratory exercises on your CD are not be updated. On your own and without assistance, complete this Lab 2 Answer Form electronically and …

In order to determine the effect of the substrate on the rate of respiration of yeast, Durham test tube method was used in the first experiment. In this method two test tubes was obtain, where test tube one contains distilled H20 with the 7 ml substrate glucose while test tube …

The following tests will record positive (+) reactions or negative (‐) reactions to fructose, sucrose, cellulose, starch, lactose and an unknown carbohydrate. Observations and Results Report your test results in a tabular format • Record the bacteria identified in each of the Four Media Tests. Test Bacterium 1 Test Bacterium …

Every living thing is dependent on large complex molecules, known as macromolecules. The objective of this lab was to correctly identify which macromolecules the unknown solution was comprised of using various substances as experimental controls. There are four major types of biological macromolecules – carbohydrates, lipids, proteins, and nucleic acids …

The purpose of the lab is to learn how to determine the presence of glucose, starch, lipid, and protein in various samples through standard tests. MODIFICATION1. Protein solution, vegetable oil, glucose solution, sucrose solution, starch solution and distilled water were added separately into six marked test tubes. The volume added …

Four environmental factors of enzymes were tested in lab. The changing of pH, substrate concentrations, temperature, and an inhibitor (NaCl) and the effects it hade on the enzyme turnip peroxidase. Enzymes are biological catalysts which increase reaction rates by lowering the activation energies of substrates. A substrate is a reactant …

My experiment was to find out the effect of changing the copper sulphate concentration on the rate of the hydrolysis of starch to maltose using the enzyme amylase. Copper sulphate was used because it acted as an inhibitor. Hypothesis, I predicted that the more copper sulphate added to the solution …

Hypothesis. The hypothesis that I draw is that “” out the five carbohydrate substrates that I will use, Glucose will produce the highest volume of Carbon Dioxide at every five-minute interval. Null Hypothesis. The null hypothesis that I am composing is that “” the five carbohydrate substrates that I am …

When testing urine the test results may provide information regarding the status of carbohydrate metabolism and kidney function. The kidney glomeruli act as ultrafilters for the plasma protein; however as much as 150 mg/dl of protein may normally be excreted into the urine. In glomerular proteinuria, an increase in glomerular …

This experimentation was to evaluate absorbance and the reaction rate of an enzyme, ‘-amylase in starch-iodine solution. We will be testing the relationship between enzymatic reaction affected by temperature and pH. Through the testing the enzyme at different temperatures, and different pH levels; it would determine at which temperature and …
