Sugar Metabolism with Yeast (Carbon Dioxide Gas)

Experiment #10A from Investigating Biology through Inquiry

In the Preliminary Activity, you will use a CO2 Gas Sensor to determine the rate of respiration of glucose by yeast.

After completing the Preliminary Activity, you will first use reference sources to find out more about sugars, respiration, and yeast before you choose and investigate a researchable question dealing with the respiration of sugars by yeast. Some topics to consider in your reference search are:

  • sugars
  • carbohydrates
  • monosaccharides
  • disaccharides
  • polysaccharides
  • yeast
  • glycolysis
  • metabolism
  • aerobic respiration
  • anaerobic respiration
