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).
