HOW DOES THE CONCENTRATION OF A CARBOHYDRATE AFFECT THE RATE OF RESPIRATION? PLAN: Aim: The aim of this experiment is to find out which carbohydrate produces the most energy in respiration. For this I have to find out which carbohydrate is best. Prediction: Once the best carbohydrate is found, we can vary different factors to find out if the carbohydrate works best in different conditions. In this case I will change the concentration. From this I can predict that the higher the concentration, the carbohydrate will produce more energy. The greater the concentration of the carbohydrate the more carbon dioxide, water and energy will be released. My reason for this prediction is that yeast is a unicellular fungus, which feeds saprophytically and can respire both aerobically and anaerobically. In the experiment the yeast will be respiring anaerobically and breaking down the glucose stored in it as a waste product of this process...
