BIO 181 Dr. Sweat Discussion After analyzing our results, it was apparent that some made mistakes were made during our experimental procedures that affected the results. For our first experiment, we examined the effects of temperature on respiration, and experimented to see if respiration is a unique property of life. When we first set up the experiment, we did not put the items into the test tubes correctly, thus we had to repeat it, ensuring no mistakes were made the second time around. When we finally set it up correctly, we compared two temperatures and two types of peas. If CO 2 was absorbed, then oxygen was consumed, causing the levels go down. We were able to confirm our hypothesis that living peas would respire more than heat-killed peas, and that at higher temperatures, more oxygen was consumed. For our second experiment, we looked to determine what the effects of MgSO 4 and NaF are on anaerobic respiration. Being that sodium fluoride is an inhibitor, we expected respiration to occur at a lower rate than the tube containing magnesium sulfate. Respiration rates increased in the presence of MgSO
