An investigation to see how different sugars affect the growth and respiration of yeast Introduction The aim of this investigation is to see how different sugars affect the growth and respiration of yeast. I will do two different experiments for the rate of respiration. One will be by using a burette and the other will be using a solution of methylene blue to measure the rate of respiration by analysing if the yeast cells are still active. To see how the different sugars affect the growth of yeast you can do two experiments, using a haemocytometer and a colorimeter. These two pieces of equipment are used to measure the growth of yeast. The different sugars I will be using are Glucose, Sucrose, Fructose and Maltose. From my previous knowledge obtained in AS Level I have found out that Glucose is made by one glucose molecule. This means it is a monosaccharide....
