The Affect of Temperature on the Rate of Cellular Respiration Loading In this experiment, we examined how temperature affects an organism’s rate of respiration. Enzymes important in the process of cellular respiration are not able to perform as effectively and slow down in the cold water, therefore cellular respiration is decreased as well. Cellular Respiration Cellular respiration is a series of metabolic processes which all living cells use to produce energy in the form of ATP. Introduction: We need fuel for our body to function; we get this fuel from the food we eat in the form of proteins, carbohydrates, and fats. As temperatures rises from freezing, the respiration rate of a mammal will actually go down because less energy is needed for heating. Do you think the dormant dry peas respire as much as the germinating peas? Why or why not? 12. Therefore increasing the temperature will raise the average kinetic energy of the reactants, which will enable a larger number of reactions to occur. Germinating and dry lima beans, pinto beans, and peas were tested. Glycolysis uses ten specific enzymes in a chain reaction to help breakdown glucose into two molecules of pyruvate (C3H6O3). This happens when cells combine O 2 and glucose to make ATP (adenosine triphosphate), CO 2 and water. As shown in the data table for the worms, crickets, and glass peas at room temperature, 21°C, the glass beads as expected showed no change in oxygen consumption as they do not perform cellular respiration, and the cricket consumed much more oxygen than the worm, which did not consume much oxygen at all. The ideal gas law and its concepts are reviewed and applied. The entry of glucose into a cell is controlled by the transport proteins that aid glucose passage through the cell membrane.
