Planning PROBLEM TO BE INVESTIGATED Yeast enzyme specificity: Specificity of Brewers and Bakers yeast enzymes to different sugars (being monosaccharides) HYPOTHESIS I predict Bakers yeast to have a different enzyme specificity compared to Brewers yeast where more CO2 is produced at 37 0C. BACKGROUND KNOWLEDGE Fermentation is the breakdown of sugars by bacteria and yeast using a method of respiration without oxygen (anaerobic respiration). It involves a culture of yeast and a solution of sugar, producing …showed first 75 words of 705 total…

Risk Assessment and Ethical implications A warm water bath will be used which may be slightly dangerous in that you can be burnt, I will be dealing with an electrical device therefore I should take great care not to touch plugs with wet hands. I will be using living organisms (yeast) in my experiment however they will not be killed for or during the experiment.
