BIO 141 Lab 6 ok me from the final volume to get the total volume of NaOH you used to titrate the 0% glucose-y 11. Repeat steps 8-10 for o owor the remainder of the glucose yeast solutions. Be sure to e buret. You always want at least 40 mL in the buret solution watch tho NaOH level in th before you begin each titration. 12. Complete Table 1 and Table 2 on the Results page. 13. We can now determine the rate of respirat ion (in units of M/g.hr) using the efer to the information below on the interpretation of each your calculations on the Results page in the designated spot. Nc-Nel Where, A- rate of respiration (in JM CO per gram of organism per hour) NO= number of CO2 of control organisms New number of HM CO, of the experimental organisms W- mass of organisms in grams Ta time in hours. To calculate W, we will use an estimate. To make the yeast solutions, we added 3.5g of yeast to 300mL of water. Based on the volume of the small tube, calculate the amount of yeast in g that was used in each trial. The sample of 0% glucose serves as the control. Calculate four values of R using the M CO2 for each 0.5%, 5%, 10%, and 20%. Record your calculations in the results section of your lab. 14. Graph your respirometer data by hand and attach to your report. To create this graph, use a column format and 3 axes. The left vertical axis should be labeled Volume, the right vertical axis should be labeled Rate, and the X axis should be labeled Percent Glucose. See below for a simplified illustration of this, where the left column bar is for volume and the right column bar is for rate. Rate Volume Rate Percent Glucose INC NE 103Explanation / Answer
