Influence of temperature change on the respiration rate of glucose yeast cells The purpose of this study was to investigate the effect of temperature on the respiration rate of glucose yeast cells. Since yeast cells consume glucose during exhalation, carbon dioxide is released. The reaction rate can be measured using a measure of the volume of carbon dioxide gas released over a set period of time. Collecting large amounts of carbon dioxide gas within this set-up time would indicate a fast reaction rate.
The purpose of this experiment was to investigate the effect of different amounts of substrate on yeast respiratory rate and to compare it with the effect of different amounts of glucose on yeast respiration rate. The substrate I selected for further study was fructose. Fructose is a kind of fruit candy, with one of the three with dietary monosaccharides that are absorbed directly into the blood during digestion, along with glucose and galactose. Dependence: The amount of carbon dioxide produced, that is, yeast respiration rate control: 2% yeast solution (1 g, 5 g, 0 g, 5 g) (20 cm 3) Initial temperature of yeast solution (35 to 40 ° C), measurement of reaction time (180 sec)
Prediction: I think it affected the size of yeast sugar breath. Therefore, the ratio of carbon dioxide produced by comparing with maltose (disaccharide), I shows that the rate of carbon dioxide (carbon dioxide gas) produced by glucose (monosaccharide) is higher than that of glucose (monosaccharide) I believe that. "A glucose is a glucose having a hydroxyl group in the ring below." Compared with the structure maltose, "two glucose units bound together to coagulation" which can be understood as having maltose taken into account Compared to two glucose subunits, maltose, glycosidic linkage: disaccharide maltose, two separate α-glucose monosaccharides, provided that "maltose with a ratio of two additional key glucose monomers can be observed In between the keys. "Compared to monosaccharides, this combination slows down the destruction of yeast producing carbon dioxide during respiration and the disaccharide ratio
