Cellular Respiration Lab ReportI.IntroductionIn this research laboratory we are measuring the amount of oxygen used in some(prenominal) germinating and non germinating peas. We are measuring the oxygen consumption by taking a reading of a respirometer submerged in two water baths. The world-class bath bequeath be cold water and the second speedy to determine the effect of temperatures on oxygen consumption. Our negative control will be glass beads to measure to increase or falling off in atmospheric pressure or temperature changes. There is a right away relationship between oxygen consumption and Carbon Dioxide produced, therefore the to a greater extent O2 consumed the more(prenominal) carbon dioxide produced. To keep the amount of CO2 produced from canceling out every pressure gained or lost from the consumption of CO2 we are adding KOH(Potassium Hydroxide) to the respirometers. Since the CO2 will be selectively removed the change in the muckle of gas in the respirometer s hould be directly related to the oxygen consumed. In this experiment the germinating peas, in both water baths, should consume much more oxygen than the non-germinating peas or the glass beads, because germination has began thus accelerating cellular reactions and the vagabond of respiration. The cold water bath should slow the respiration down in all three respirometers. II.Materials and Procedures.For this experiment we have prepared to water baths. one and only(a) bath is ice water, around 10 degrees Celsius, the other warm, around 25 degrees Celsius. Both water bath...
