Respirometers are devices that measure these types of gas volume changes, and therefore provide information about the rate of cellular respiration. Another method is to measure either the oxygen consumption or the carbon dioxide production. One method involves monitoring changes in temperature since the process of respiration is exergonic (produces heat). There are several methods of indirectly measuring the rate of cellular respiration in organisms. Carbon dioxide and water are products of the series of reactions involved in cellular respiration. This process is called cellular respiration which requires nutrient molecules and oxygen. Cells accomplish this task by breaking down nutrient molecules to generate ATP (adenosine triphosphate), which can then be used to run cellular processes that require energy. Understand the relationships between temperature, pressure and volume.Įach individual cell is responsible for the energy exchanges necessary to sustain its ordered structure. How does the respiration rate of a germinating see differ from that of a dormant seed?.How is respiration rate affected by temperature?.How can repiration rates be measured using a respirometer?.
