Analyzing Yeast Metabolism Under Aerobic & Anaerobic conditions
Division:Physical & Mathematical Sciences / None
Region:Chignecto East
City:RR#2 River John, NS
School:Northumberland Regional High School
Abstract:Yeast metabolism under aerobic and anaerobic conditions produces different amounts of carbon dioxide. The amount of carbon dioxide produced was measured under both of these conditions using bread yeast. It was also measured after doubling the sugar and increasing the temperature. Each experiment was conducted three times for twenty minutes each. Aerobic metabolism was always faster and produced more carbon dioxide than anaerobically.
