Lab Report Yeast Fermentation
Lab 6: Fermentation
Introduction
All heterotrophs go through the process of cellular respiration in order to make energy. To obtain the most energy per glucose cellular respiration is done by aerobic cellular respiration, but when no Oxygen is present fermentation is used. Fermentation is the anarobic process that most organisms and fungi use. It involves the breakdown of glucose into alcohol if no Oxygen is present. CO2 is also produced during this cycle.
Temperature and environment can affect the process of fermentation. In this lab, we will be measuring the amount of CO2 produced in different temperature. If we have different temperature of yeast (0*, 22*,37* and 100*). The yeast solution will have no activity or very little to measure at 0*. Temperature at 37* would show the most activation or CO2 production. The yeast solution at 100* will show no activity because that high of a temperature will cause denaturing to occur.
Materials
• Obtain Fermentation tube
• Test tube
• Ice
• thermometer
• Yeast/Sugar solution
Methods
Obtain 4 fermentation tubes and label each A, B, C, D

Our experiment supports the hypothesis that the rate of carbon dioxide would increase by the increase of temperature up to a certain point, where the production of carbon dioxide would start to decrease because of the highest temperature causing the enzyme to denature. We ran into some errors during this lab with the yeast. We weren’t able to get the yeast to activate after two different trials of making the yeast solution. I’m not sure what was causing the yeast to not activate maybe the yeast or even the tap water. Next time maybe using distilled water instead of tap water, because impurities in the water can alter the carbon dioxide in the water. There are many steps that could have been done to improve this experiment and doing more than one trails of the experiment can show more
