What is the significance of these pathways for organisms? What types of organisms use cellular respiration? What types use fermentation? What are the roles of glucose, CO 2 and oxygen in these pathways? Explain the differences between mono-, di- and polysaccharides in terms of their potential use as a food source. What is a redox reaction? o What role do redox reactions play in the Citric Acid Cycle? o What role do NAD + and FAD play in these reactions? o Which redox reaction was observed in the experiment? o What role did DPIP play? What are the goals of the experiments? Include your hypotheses for the experiments. Materials and Methods (1-2 pages) Explain in detail how each part of the lab exercise was done; include any changes that were made to instructions in the manual. Describe the analytical method used (i.e. measurement of CO 2 , graphical representation of results, calculation of reaction rates) Do NOT include a list of numbered steps as found in your lab manual, but write a concise, original narrative describing what was done.
2 Organize your methods into appropriate subsections with their own subheadings. Results (1-2 pages, not including tables and graphs) Written description of the fermentation results
