Description

Yeast Fermentation Fermentation is a process that happens in both plants and animals. Yeast fermentation occurs in plants and results in the production of ethanol and carbon dioxide. Within animals or rather animal cell the fermentation process happens in the cytoplasm and generates lactic acid, this is called lactic acid fermentation. Cells use fermentation when there is a lack of or no presence of oxygen. Because it is hard to measure the efficiency within animal cells more often than yeast is used to measure. Within this this trial we can observe how efficiently the yeast can ferment different sugars. By using different sugars, we can observe how each of the different compositions are processed. Using mono,di, and poly saccharides you can compare how the fermentation process takes place. The highest rates of fermentation occurred within the disaccharide, and following closely was the monosaccharides and lagging was the polysaccharides. By recording the change overtime and the size of the CO2 bubble we could see the rates of fermentation. Because fermentation results in CO2 by recording the size of the bubble we can see how much was processed in the allotted amount of time. You would think that because the monosaccharides are the most simple that they would have the fastest rate of processing but after recording the results it can be seen that in fact the disaccharides had the most efficiency....
