Peas and Beads Lab Conclusion All living things respire whether or not they use anaerobic respiration or aerobic respiration. In this particular lab, we measured speed of aerobic respiration at two temperatures to determine whether respiration is faster at higher temperatures or at lower temperatures. The equation for aerobic respiration is as follows: C 6 H 12 O 6 + 6O 2 6H 2 O + 6CO 2 + Energy The speed of respiration at constant temperatures can be determined by either measuring amount of oxygen (O 2 ) consumed, amount of carbon dioxide (CO 2 ) produced, or amount of energy released. In Laboratory 5: Cellular respiration , we determined speed of respiration of peas in comparison of two fixed temperatures by measuring the amount of Oxygen consumed with respirometers. The subjects in the respirometers were 9 mL of germinating peas, 9 mL of dormant peas and additional plastic beads (to make volumes constant among all respirometers), and 9 mL of only plastic beads, as a control treatment. There were 2 respirometers containing each amount of peas and/or beads. Three of those respirometers were to be immersed in water at temperature 10º C, and the other three were immersed in water at temperature 21º C (room temperature). At the bottom of each respirometer was Potassium hydroxide, which interacted with
