The Effect of the Nature of Substrate on Cellular respiration of yeast

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 starch, lactose and distilled water did not aid in…
