Cellular respiration is a process that living organisms go through to get energy from organic molecule and remove waste products. The main purpose of cellular respiration is to create and gain chemical energy in the form of adenosine triphosphate (ATP). Cellular respiration divided in two to part of chemical reaction called aerobic and anaerobic reaction. In order to synthesize energy three different stages in cellular respiration occur in both reactions. Some of the stages are anaerobic reaction like glycolysis and citric acid cycle because they do not need oxygen to make energy. On other hand, oxidative phosphorylation is aerobic reaction because it produces energy with the assistance of oxygen molecules. Fermentation is the process of making energy from glucose and carbohydrate in the absence of oxygen The objective of this experiment is to …show more content…
After we left the yeast mixture in different temperature for 15 minutes we pored to different tube. We waited for five minute, and we measured the bubble level or carbon dioxide within 5 minute interval for fifteen minutes. Result We can say from this result that, there is a least almost zero fermentation process occurs in cold temperature .Similarly, the test tube that was placed in high temperature also showed less bubble level. The test tube which is placed at 40 0C had good bubble reaction than cold and high temperature level. The test tube which is placed in room temperature shows the highest bubble reaction. According to this experiment result, we can say our hypothesis is right. We predicted that there will be less fermentation process in cold temperature. Sample Temperature Time Bubble results Test tube 1 4 0c 5min 10min 15min 0cm 0.5cm 1cm Test tube 2 250c
