Cellular Respiration and FermentationI.Purpose We will be looking into both fermentation and respiration. We will be observing the reactions that take place around these two processes. Oxidation and reduction both play very valuable parts of both the reactions in cellular respiration and fermentation. Also, we will learn about how enzymes affect environmental activity and we will be observing how spectrophotometer can measure respiration. II.ProcedureWe obtained four flasks and added enough tap water about 5 cm from the top of the flask. The flasks were labeled 1, 2, 3, and 4. To stabilize each flask, a 3-inch donut-shaped metal weight was placed over the neck of the flasks. Four other test tubes were obtained and labeled 1-4. Solutions were added as seen in table 1. To each tube, 1-ml of a graduated pipette to which a piece of plastic aquarium tubing has been attached. The flasks were then placed with the test tubes and graduated pipettes in the water bath at 30 degrees Celsius.
