The graph shows that the higher the concentration of sugar the lower. the respiration rate. I believe this is because the more amount of. sugar added the more yeast die. This is due to either: 1.The high concentration of ethanol produced as a by-product. poisoning the yeast. 2. The temperature of the reaction being too high causing the yeast to. die or the enzymes to be denatured.. The temperature of the reaction, as some of the energy produced. converts into heat energy. At really high temperatures the reaction. will stop because the heat will have denatured the enzymes. 3. When there is a high sugar concentration the sugar molecules. diffuse into the yeast.
