In fermentation, pyruvate is converted into either ethanol (yeast) or lactic acid (animals and bacteria), and carbon dioxide. In yeast, the 2 pyruvate molecules are broken down into 2 CO2 molecules and 2 acetaldehyde molecules. The acetaldehyde is then converted into ethanol with the addition of a hydrogen ion from NADH. The NADH then becomes NAD+ and assists in glycolosis

  1. Occurs in yeast
  2. Pyruvate is broken down
  3. Releases CO2
  4. Creates ethanol
Lactic acid fermentation:
  1. Occurs in animal cells and some bacteria
  2. Pyruvate is directly reacted
  3. No gasses released
  4. Creates lactic acid

One gram of yeast was then put in the tube, on top of the liquid. The rest of the tube was filled tot the brim with its liquid. A persons thumb is placed at the top of it and the tube is inverted a couple times. A slightly larger tube is put over it and both tubes are flipped together. Once all four of the tubes have gone through this process, they are put in an oven at 40o Celsius for twenty minutes. Afterwards, the gas levels are observed and recorded.]]> 2018-10-24 17:40:50 UTC https://padlet.com/email4125/jcuzxxsq90e1/wish/296594043 Fermentation Lab Results jill_schroedl https://padlet.com/email4125/jcuzxxsq90e1/wish/296595949 2018-10-24 17:43:46 UTC https://padlet.com/email4125/jcuzxxsq90e1/wish/296595949
