Factors effecting the rate of respiration in immobilised yeast I am looking at yeast to find the optimum conditions for it to produce more carbon dioxide as a waste product from breaking down glucose during anaerobic respiration. This occurs when there is too little oxygen available to enable yeast to respire aerobically in order to produce ATP. Anaerobic respiration is a type of respiration in which carbohydrates are partially oxidised, with the release of chemical energy, in a process, which does not involve oxygen. Since the substrate is never completely oxidised the energy yield of this type of respiration is lower than that of aerobic respiration (A single molecule of glucose can produce 38 molecules of ATP in aerobic respiration and in anaerobic respiration it only produces 2 molecules of ATP. It occurs in some yeasts and bacteria and in muscle tissue when oxygen is absent. Saccharomyces cerevisiae are facultative...
