Botany Lab ------------------------------------------------- Introduction This study observed the effects of different body fluids and solutions relative to breaking down bacteria‚ specifically in the human body. The enzymes we studied‚ lysozomes‚ help the body lyse‚ or break down bacteria by targeting peptidoglycan in bacterial walls. The solutions and fluids studied were saliva‚ mucus‚ tears‚ a stock solution of lysozomes‚ and distilled water. The solutions were placed in agar containing Micrococcus

The Catalase Lab Stephen Human Anatomy & Physiology 9/30/12 Problem- How do different environments affect the reactivity of catalase? Hypothesis- If more catalase is added then more oxygen (kPa) will be produced in a faster rate because there is more catalase to react upon. If less catalase is added then less oxygen (kPa) will be produced in a slower rate because there is less catalase to react upon. Variable- Independent- Amount of Catalase (Filter Paper) Dependent- Amount of

5%‚ 27%‚ and 30%. The Vmax of the inhibited reactions was 1.208 mL/s and the Km was 7.033M (figures 3.3 and 3.4). Generally‚ reaction rate increased with substrate concentration. A paired t-test was performed comparing the velocities for the inhibited (exp. V) and uninhibited (exp. IV) reactions. This t-test presented a p-value of

Three test tubes were filled with 5 mL of A‚ B‚ and C‚ respectively. 10 drops of mammal blood was added to each of these and mixed. The transparency and translucency of these tubes was tested. The solutions in the opaque tubes were placed on a slide with a drop

Constant Determining the effect mass has on acceleration Block 5 11/25/12 Purpose: The purpose of this lab is to determine the effect of additional mass added to a cart’s existing mass‚ without changing the applied force‚ on the acceleration of the cart. We will test this effect by hanging a constant mass to a cart and use a computer program‚ LoggerPro‚ to calculate the acceleration which is expressed through the slope of the graph

Title: The Effect of Varying Amounts of Substrate and Enzyme on a Reaction Rate Abstract In living organisms‚ certain reactions must take place rapidly to assist life. This occurs because of enzymes‚ because all reactions would take place too slowly to sustain life (Jacklet‚ 237). Enzymes are large protein molecules that catalyze specific chemical reactions without being used up in the process. Each enzyme has a region on its surface‚ called the active site‚ which recognizes a specific

The mean hemolysis times of sheep erythrocytes in 0.3 M urea‚ thiourea‚ methanol‚ ethanol‚ propanol‚ ethylene glycol‚ diethylene glycol‚ and triethylene glycol were calculated‚ and paired‚ two-tailed t-tests were conducted to determine statistical significance. It was found that the difference in hemolysis time between methanol and ethanol was not statistically significant (P = 0.0666‚ t = 2.0577‚ df = 10); the same result was found between the results

with quadrants that contain the culture‚ a hemacytometer‚ was used to carry out this experiment. After the data was collected from using the hemacytometer‚ the results of the difference between the two cultures was to be determined through a t-test. As the test was conducted‚ the study shows that the difference between lacking an antibiotic and containing one is not different. An antibiotic in culture-A and culture-B does not affect the number of yielded yeast cells. Introduction. -- It is undetermined

Introduction:- The primary objective of this experiment is to determine the concentration of an unknown copper (II) sulphate solution. You will be using the colorimeter. In this device‚ red light from the LED light source will pass through the solution and strike a photocell. The CuSO4 solution used in this experiment has a deep green color. A higher concentration of the colored solution absorbs more light (and transmits less) than a solution of lower concentration. [Content Standard B- Structure

Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What
