Cellular Respiration Experiment
Abstract The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast, smith fermentation tubes and different substrates namely, starch, lactose, sucrose, glucose and fructose, which are from different kinds of carbohydrates, ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control, the hypothesis was tested. With the span of thirty minutes with five-minute intervals, the height of carbon dioxide trapped in the tube was measured. The results showed that with the substrate fructose, the rate of carbon dioxide (2.51 ml/min) production was highest followed by sucrose (1.60 ml/min) and lastly, glucose (0.83 ml/min). The remaining three namely

One of these metabolic processes is cellular respiration.
Cellular respiration is a catabolic process that can be classified as either aerobic or anaerobic depending on the presence or absence of oxygen. It basically uses sugar and water as reactants and water, carbon dioxide and energy as products. This process is essentially a reverse process of photosynthesis that reciprocates the reactants and products (Campbell, 2011). This experiment focused on the anaerobic respiration of yeast.
A catabolic process or catabolism is a degradation or a break down process that releases energy. It converts complex materials into simpler ones like how proteins can be turned into amino acids (Lewis, 1997).
There are two types of anaerobic respiration or fermentation, lactic acid and alcoholic. In lactic fermentation, pyruvate is converted to lactic acid that happens without the presence of oxygen. It usually happens in muscles when oxygen levels are low but respiration still continues that results in the formation of lactic acid within muscles. Alcoholic fermentation, on the other hand, produces ethanol and carbon dioxide (Chiras, 1993).The latter type of fermentation was observed in this experiment with the use of
