A metabolic pathway in yeast using immobilisation Conclusion As you can see from my graph there is a basic trend. This is that as the carbon dioxide increases with time the rate of reaction increases for the yeast. The volume of carbon dioxide increases because the yeast is respiring anaerobically; the yeast breaks down the glucose and produces carbon dioxide and alcohol as a waste product. This process is fermentation. The equation for this reaction is: Oxygen + Glucose Ethanol + Carbon dioxide + Energy (O2) (C6H12O6) (C2H5OH) (CO2) The carbon dioxide is produced because the substrate (sucrose solution) binds to the active site of the enzyme (free yeast). The active site is an area of an enzyme, which the substrate fits in order to catalyse a reaction to which carbon dioxide and alcohol is produced. Immobilised enzymes are enzymes bounded immovably to a surface and not allowed to dissolve in a solution. Also looking...
