Yeast Fermentation free essay sample

Temperature will affect the growth of yeast cells if it becomes abnormally high or low. Temperature speeds up chemical processes because the atoms move faster, and enzymes are proteins that catalyze chemical reactions and function in the satisfactory environmental conditions. However, when the temperature is increased and the enzymes are exposed to a large amount of heat which they were not made to withstand, the enzymes become denatured. When temperatures are lower than their sual standard, enzymes do not have enough heat to power the reactions and therefore become useless. So, if the temperature is too high or low then the yeast will not be able to go through fermentation. For sugar, monosaccharides such as glucose or fructose seem more suitable for fermentation than disaccharides, because the yeast does not have to break down the sugar. Fructose should be as suitable for fermentation as glucose because of their imilar chemical formula.

Water activity in yeast fermentation seems like it needs to be a medium level amount. Increasing the amount of water, without adding any other substrates, such as sugar, would result in an excessive amount of water that would dilute the substrate and would not allow the yeast to go through fermentation. If the xperiment lacked water, then the yeast cannot break down the sugar through hydrolysis and Every enzyme has its own pH level that it works best on. For yeast, it seems to function best in a neutral or slightly acidic environment. By significantly lowering the pH and making it more acidic, the solution could denature the enzymes in the yeast. If the solution were higher and more basic, the enzymes of the yeast would not be able to function properly because it level of pH is not the optimal one needed.
