This is used to prove that fermentation produces CO2. Mix sugar water and yeast in the bottle. Place balloon opening over the top of th bottle and secure with string so that nothing can enter or exit the system. Enough CO2 will eventually be created to blow up the balloon. Is that what you wanted to know?

Put the yeast into the bottle with some warm water (not too hot) and sugar. Tie the balloon over the neck of the bottle with string and leave in a warm place. The balloon will expand as it fills with gas from the mixture in the bottle. Prove that this gas is carbon dioxide by passing some through lime water and seeing the water go cloudy

Production of CO2 is Dependant On Oxidative Metabolism, Not Fermentation, So, When the Cells (Most In Replication) Are Growing, CO2 is Produced. There Two Things Going On Here. Glycolysis (Primarily In Fermetation) and Oxidative Metabolism (In the Mitochondria, Much More ATP).
