The reactions and Results of Using Enzyme Turnip Root Peroxidase Lab results from: Andrew Compton‚ Mickey. Results published 9/29/2012. TA: In this series of laboratory experiments‚ my lab partner and I were to conduct an experiment about the oxidation rate of the enzyme peroxidase in the presence of its substrate guiacol. Also we used other substrates‚ such as hydroxylamine an enzyme inhibitor‚ to observe the weather the reaction rate was slowed down‚ sped up‚ or stopped reactions all together

LAB 1 1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points) a. Eye Wash (2 points) The eyewash fountain is used to rinse chemical splashes off the eyes. They are used by rinsing the eyes 15 to 30 minutes with water. b. Fire Blanket (2 points) Fire blankets are used to extinguish small fires. They are used by covering the small fires with the blankets until it extinguishes. c. Shower (2 points) Safety showers were made to eliminate any

Aim: 1) To determine the effects of different salt concentration on the percentage of weight change in potato cubes 2) To determine the isotonic solution concentration for the potato Hypothesis: 1) If the concentration of the salt solution is higher than the concentration in the potato cubes‚ the percentage of weight change in potato cubes will be higher (positive). If the concentration of the salt solution is the same as the concentration in the cell‚ there will be no net movement of water through

that live in the water‚ their oxygen has to be obtained from the water. The amount of oxygen that these organisms can take from the water is hugely dependent on the dissolved oxygen content in the water. The purpose of the two experiments done in this lab was to see the ideal condition to produce the most dissolved oxygen concentration. We approached the challenge of finding the ideal condition by testing two different variables in two different experiments. In the first experiment‚ we tested the different

TITLE AND AUTHOR Lab 7 Analysis of purified Concanavalin A via:Hemagglutination INTRODUCTION The purpose of this lab was to test the biological activity of ConA by performing a hemagglutination assay. If ConA is active then agglutination will occur due to ConA’s free receptors being able to bind to the glucose residues on the sheep’s red blood cells. If ConA is not active then no agglutination will occur. To test the hemagglutination reaction‚ two types of ConA solutions

II. Genetic variation is accounted for in Meiosis I due to crossing over. No formal hypothesis was made due to the fact that this lab was a simulation and observation of prior knowledge. The lab did not go as expected for prophase was supposed to be the second longest phase in exercise 3A but Metaphase ended up with the higher percentage (Table 3.1). Because this lab was solely based on observation‚ there was little space for error‚ but as mentioned above‚ metaphase ended up with the higher percentage

Plant Pigments and Photosynthesis Problem: We are going to separate and identify pigments and other molecules from cell extracts through a process called chromatography. We will also test the theory that light and chloroplasts are required for light reactions to occur. Background: Pigments are chemical compounds which reflect only certain wavelengths of visible light. This is what makes them seem colorful. Many things contain pigments including flowers‚ corals‚ and even skin. More important than

Evolution Lab “Evolution by Natural Selection” The object of this experiment is to determine how changing the size of the beak of a finch will affect the population as well as the growth rate of the finch’s beak. The reason for the experiment is to evaluate evolution and how it affects the finch’s population‚ and how natural selection is always present in life. In this experiment I will show that the finch will continue to evolve until its beak has reached the optimal size for sustaining
