Fermentation Lab Introduction For bacteria and many single-celled protists fermentation is a common anaerobic pathway that the cells use to collect energy from carbohydrates to form ATP. The process for fermentation begins in the cytoplasm with a process called glycolysis‚ which converts one molecule of glucose into two molecules of pyruvate. When glycolysis is complete four ATP would be produced but the net yield would be two ATP taking into account the initial investment of two ATP

In the lab‚ the purpose was to standardize a KMnO4 solution than using it to evaluate how close a H2O2’s concentration was to its labeled concentration. In this lab‚ it was decided to compare the concentration of new Publix brand hydrogen peroxide to an old sample of the same solution. From the data collected in the first part by titrating a solution of FeSO4*7H2O with the KMnO4 solution‚ it was determined that the concentration was .028M MnO4-. This was able to be done because a known amount of

10.19.2011 TITLE: The Importance of Oxygen for Life PURPOSE: To determine whether test tubes filled with bacteria‚ a few salts‚ distilled water‚ and glucose would grow in the presence or absence of oxygen. By adding oxygen to certain tubes and withholding it from other tubes‚ one can determine which bacteria grow the most efficiently. HYPOTHESIS: The test tubes of bacteria with oxygen will grow and thrive over the test tubes without oxygen. METHODS: Using the data shown in Table 7-A-1

Every cell‚ whether it belongs to a plant‚ bacteria or a human‚ requires energy from varying food sources to survive. However‚ when cells break down food into its sugar components‚ i.e glucose‚ they cannot use the components directly because glucose holds a lot of energy it would be inefficient to use for reactions that don’t need a lot of energy. Imagine you want to buy pencils for $5 from a store that won’t give change‚ it is more economical to use a $5 or $10 bill than a $100‚ that way there is

Hypothesis: The closer the light is the plant‚ and the higher the wattage of the light‚ the faster the rate of Photosynthesis. So‚ the 150 watt light bulb at 5centimeters will have the highest rate of photosynthesis.

152-35 Professor Weller 14 February 2012 Effects of Temperature on Goldfish Respiration Introduction This experiment was designed to identify the effect of cold-water temperatures on the respiration rate of goldfish. The respiration rates helped to identify the goldfish as being ectotherms or endotherms. Organisms exchange gases with their environment through a process called respiration or breathing. Aerobic respiration‚ also known as aerobic metabolism‚ occurs when oxygen is taken into the body

Im a junior scientist for MitoSciences. I have been given the task of organizing and analyzing the results from a prior experiment my supervisor Ms. Ehnar Jiy conducted. In this lab‚ i wanted to know if more active cells in our bodies require more energy. I started of by taking five samples of three different types of cell (skin cell‚ muscle cell and lung cell) and counted the mitochondria present in each by viewing the cells under a powerful optical microscope. According to my data‚ i found out

function. In photosynthesis and aerobic cellular respiration energy is being produced to cycle carbon between the functions. There is the function of maintaining life‚ helping aid chemical reactions‚ using the cell to help aid reation. All of these recycling processes help creates energy that is then in return used to aid their specific function. The life processes of nutrition and respiration are related to photosynthesis and Aerobic Cellular Respiration. All organisms use material from the outside

cell‚ the vacuole that is responsible for storage and the maintenance of osmotic balance can be located. In this study‚ we are using beets to study these cellular structures. Beet is a plant whose cells contain a characteristic red pigment‚ called betacyanin. It is located in the vacuole‚ which is surrounded by the tonoplast membrane (Biology 107 Lab Manual 2010-2011). In order for the betacyanin to remain inside the cell‚ the membrane must stays intact; otherwise betacyanin will leak out of the vacuole
