This study determined whether or not temperature had an affect on CO_{2} production between yeast and different sugars. For this experiment, 2 mL of 10% fructose solution, 10% glucose solution, and distilled water were each combined with 2 mL of baker’s yeast. Each of these three solutions was measured for CO_{2} production at three different temperatures: 3 ºC, 22 ºC (room temperature), and 42 ºC. None of the solutions produced CO_{2} when they were at 3 ºC. At room temperature, the fructose and yeast solution produced 0.37 mL of CO_{2} in 60 minutes, while the glucose and yeast solution produced 0.45 mL of CO_{2} in 60 minutes. The control sample did not produce any CO_{2}. At 42 ºC, the fructose and yeast solution produced 1.28 mL of CO_{2} in 45 minutes, while the glucose and yeast solution produced 1.33 mL of CO_{2} in 45 minutes. Again, the control group did not produce any CO_{2}. Temperature had a great impact of the production of CO_{2}. When chilled, the solutions did not even produce any CO_{2} at all, but when heated, the solutions produced CO_{2} almost four times as fast as normal.
