... concentration. As carbon dioxide is converted into a solid, the net pressure of the gas and the volume decreases. Metabolic processes are important in the production of ATP. Metabolism regulates cellular activities. The pathways regulate the catabolic breakdown of glucose molecules. By harnessing the energy in the glucose molecule in small pieces, the cell conserves and prevents the loss of this energy. Each step in cellular respiration insures that the energy in the glucose bonds is conserved. The amount of cellular respiration reflects the amount of activity in the cell. In order to produce energy and continue living, cells perform cellular respiration. Thus, cells that perform cellular respiration more are also more active. There are three ways that the amount of cellular respiration can be measured: the consumption of oxygen, the production of carbon dioxide, and the release of energy. Hypothesis: If a respirometer only contains germinating peas and is placed in ...
