Tiffany Cho AP Biology Lab Report #7 October 14, 2008 What is fermentation? Observations- Cellular respiration is a cell’s way of making ATP for all cell processes. It is done in two ways, anaerobicly and aerobicly. Both begin with the simples of sugars: glucose, because it is the fuel that cells most often use. Anaerobic respiration occurs without using oxygen at all, also known as fermentation. For unicellular organisms, fermentation is a partial degradation of sugars that releases about 2 ATP, a very small amount of energy. It incompletely breaks down glucose and energy tends to remain mostly in the organic molecule. Aerobic respiration, most often what cellular respiration is referred to as, is usually for multicellular organisms, releasing 36-38 ATP. It completely breaks down glucose to inorganic molecules. Overall, the process is organic compounds + oxygen carbon dioxide + water + energy. Yeast is used to ferment carbohydrates. Glucose and fructose are monosaccharides and sucrose is a disaccharide that contains glucose and
