highest rates and that lactose was the lowest‚ so we see a clear downwards sloping trend‚ which was also expected. This suggests that yeast respires best with glucose instead of sucrose fructose or lactose. To explain this process‚ we must first understand how sugar affects yeast growth. First of all yeast is a fungus‚ meaning that it needs sugars to supply it energy. Yeast can also release oxygen like human beings‚ called respiration. So technically speaking the more sugars there are the more

Fermentation Lab Report Hannah Newman Fermentation is the chemical process converting sugar to gases and occurs in yeast and bacteria. In the experiment we conducted‚ we used sucrose and yeast and measured the fermentation carbon dioxide formation. The factors affecting fermentation that we tested in this experiment were temperature and the effect of a disinfectant. We measured the fermentation carbon dioxide formation by using a ruler and measuring the amount of bubbles in the tube that were

PURPOSE What sugar will get the most rise out of yeast‚ so you can get the best bread or baked goods possible. Sugar when mixed with yeast and water will produce carbon dioxide. The carbon dioxide from the yeast sugar and warm water will make the balloon on top of the water bottle blow up. I hypothesize that brown sugar will make the balloon blow up the most HYPOTHESIS If I were to mix brown sugar‚ with yeast‚ and warm water together it should have a different reaction as opposed to other sugars

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

It prevents contamination from unknown cultures. 3. Does your lab report contain any messages when your inoculation was not complete? What change in the traffic signals indicates an unsuccessful inoculation? Answer: The lab report does not contain any messages about inoculation. There’s only a reference if auto-inoculation was used. The traffic signal light will turn red if the inoculation was unsuccessful. 4. Does you lab report contain any messages when you don’t follow aseptic procedures

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

Balloon Respiration Lab Introduction/ Background Cellular respiration is a process that releases chemical energy from glucose and other carbon-based molecules to produce ATP when oxygen is present. The formula for cellular respiration is C6H12O6+ 6O2= 6CO2= 6H2O. The process of respiration contains three main parts‚ glycolysis‚ Krebs cycle‚ and the Electron Transport Chain. The process of glycolysis takes place in the cytoplasm and is considered an anaerobic process which splits glucose into two

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source
