Benny Wong 10/13/09 Tuesday Biology Lab #6 Cellular Respiration and Fermentation Purpose: In this lab, fermentation and cellular respiration were introduced. These cellular processes transfer the energy in glucose bonds to bonds in adenosine triphosphate (ATP). The energy in ATP is then used to perform cellular work. Fermentation differs from cellular respiration in the way that fermentation is an anaerobic process (without oxygen), while cellular respiration is an aerobic process (requires oxygen). Both of these processes involve redox reactions. Redox reactions are electron transfers, oxidation being the loss of electrons and reduction the gain of electrons. In cellular respiration, there are 3 stages: glycolysis, the Krebs

The first experiment conducted was observing the amount of CO 2 produced during fermentation of yeast and glucose, starch or amylase. The second experiment conducted was the redox reactions in a mitochondrial suspension, in which the transmittance of light through the different solutions were measured to indicate the speed at which the reaction is taking place. Results: Significance: Based on the data from the % change in transmittance, the amount of succinate affects the respiration rate. Succinate speeds up the respiration rate, and made the solution more clear....
