Background: Techniques used were in accordance with NMU Professor Dr. D. Becker’s lab manual (ISBN 0-390-53911- 2; McGraw Hill). Changes in protocol or interpretation are noted where they were implemented‚ but strict adherence to the manual prevailed. Materials and Methods: Microscope‚ incubator‚ and deionizer functioned correctly throughout testing period‚ with stains‚ dishes‚ agars‚ and test reagents readily available. Lab procedures are considered orthodox and usage thereof is noted chronologically

Enzyme Lab: Peter Kuetzing – 10/4/2012 – F Block 1. How does changing the concentration of enzyme affect the rate of decomposition of H2O2? When more enzymes is added the rate of reaction speeds up. In this case‚ H2O2 will produce more O2‚ in return the kpa/min will go up. 2. What do you think will happen to the rate of reaction if the concentration of enzyme is increased to five drops? Predict what the rate would be for 5 drops. I think that the rate of reaction will slightly increase from

Regents Biology Period _________ Date ______________________ LAB ____. ANATOMICAL EVIDENCE OF EVOLUTION In our studies of the anatomy and development of animals we have discovered that many living creatures that look quite different on the surface have similarities underneath their skin that suggest that they are related to each other. This is evidence that living creatures have evolved‚ or gradually changed over time. In this lab‚ you will learn about homologous‚ analogous‚ and vestigial structures

A. What is the name of the pigment that captures light? Chlorophyll B. Why does the pigment appear green? It absorbs other colors of light such as red and blue‚ so in a way the green light is reflected out since the pigment does not absorb it. 2. List two variables besides the wavelength (color) of light which might affect the rate of food production in plants. Light intensity and carbon dioxide 3. Why is chlorophyll important for all biological life? It is necessary for photosynthesis which

Lab 2 Sara Rodriguez Period 2 Purpose: What is the more accurate way to measure volume‚ by using displacement or by using a ruler? Hypothesis: If the method of displacement is used ‚ then the results will be more accurate than measuring the volume using a ruler. Materials: -250 mL graduated cylinder -Triple beam balance -A weigh boat -Ruler -Samples Procedure: 1. Gather materials such as ‚ samples‚ weigh boat‚ triple beam balance ‚ graduated cylinder‚ ruler and water. 2. Take the materials

attached at the higher end of the ramp. 2. Carbon paper was attached to the ticker machine and ticker tape was fed through to the ticker machine. 3. The ticker tape was taped to the back of the car. 4. The ticker machine was turned on (turnt) and the car was released and stopped as it exited the ramp. 5. The ticker tape which was dotted was collected and the distance between dots was recorded. 6. The process was done 3 times for each angle. 7. Steps 2-6 were repeated for 6.3 degrees‚ 90 degrees

Bryson MISEP Chemistry 512 – Jacobs Enzyme Catalyst Lab - Formal Report – August 8‚ 2007 ABSTRACT This investigation examined what would happen to the rate of an enzyme-catalyzed reaction if the concentration of substrate changed. We hypothesized that if the concentration increased‚ then the reaction rate would also increase. To test our question‚ we varied a combination of substrate and buffer‚ totaling 6mL‚ with a constant amount of 2 drops of catalyst. The enzyme catalyst‚ peroxidase
