Upload the data from the Pasco Xplorer LX to Excel and graph the CO 2 production data as a function of time for the normal and the freeze/thawed peas. Add a trendline with the slope of the line equation and the R 2 value for both types of peas. Calculate the slope of each line and enter them on Table 1. The slope of the line is the respiration rate (ml/min or mlmin-1 ). Calculate the mass-specific CO 2 production. Table 1. Mass specific carbon dioxide production (ml/min/g) for normal and freeze/thawed peas Tube Contents Slope (ml/min) Peas mass (g) Mass-specific CO 2 production (ml/min/g or ml min-1 g-1 ) 1 Normal peas 6.28x10-3 6.28 1.00x10-3 2 Freeze/Thaw 3.50x10-4 2.94 1.19x10-4 Figure 1. Graph displaying CO 2 production versus time in normal peas. Trend line slope equal to respiration rate of 6.28x10-3 mlmin-1 . Time and CO 2 production are directly related: as time increased, CO 2 production increased as well. Figure 2. Graph displaying CO 2 production versus time in frozen peas. Trend line slope equal to respiration rate of 3.50x10-4 mlmin-1 . Time and CO 2 production are directly related: as time increased, CO 2 production increased as well....
