WebExplains that the two liquids (starch suspension and yeast) will be poured in and mixed with the stirring rod. the amount of carbon dioxide produced in each of the beakers is measured and recorded. Concludes that glucose will undergo the most metabolism by yeast than starch because glucose is already broken down in its simplest form. WebClearly, maltose is the best for yeast metabolism. Remember, yeast is made of two glucose molecules. Glucose (aka dextrose) is a close second. Fructose is in third place. Interestingly, sucrose, made of glucose and fructose, does not perform well.
