Slowly add NaOH, drop by drop, to the water in the flask. COUNT the number of drops as they are added, swirling after each drop, until the solution turns and remains a faint pink color. Wal 10 seconds, If there is still a faint, but definite pink color, you have reached the end point. If the color disappears, you are very near the end point and should cautiously continue to add drops of NaOH. Record the total number of NaOH drops added in Table 7.3. Column A. 2. Using 25 mL of water from beakers 1,2 and 3 , repeat the procedures outlined in steps 9-11. 3. Multiply the number of drops of NaOH by 4 to detennine the number of drops you would have had to add to your total volume of 100 mL. Convert the number of drops to ml by dividing by 20 (1 mL=20 drops ). Record your results in Table 7.3, Column C. 4. Use the following equation to calculate the rate of CO2​ production for each organism in H moles/hr/g. Enter your calculated results in Table ll. 1.0 hour × weight of organism /g)[mLNaOH (expt.) −mLNaOH( control] ]25μmolesNaOHi/mL * ​ 4 moles/mL is the concentration unit of the NoOH you added you need not understand this] 5. Make a graph of the rate of respiration versus organism. Table 7.2. Weight of Organisms. Table 7.3, Rate of CO2​ Production. Lebaratory ? | Cellelar Respiration
2. Why was the amount of CO2​ divided by the weight of the organism? 3. Do your results support the hypothesis that organisms respire at the same rate? 4. Discuss and compare the rates of cellular respiration of the organisms and explain any differences in the rates you saw. 5. What factors with these specific organisms might make comparisons difficult? 6. How might your rate of cellular respiration compare? Explain. 7. How would an increase in physical activity affect the amount of CO2​ produced?
