When the necessary conditions are met, germination occurs, and the rate of cellular respiration greatly increases. In this experiment you will measure oxygen consumption during germination. You will measure the change in gas volume in respirometers containing either germinating or nongerminating pea seeds. In addition, you will measure the rate of respiration of these peas at two different temperatures. Introduction Cellular respiration is the release of energy from organic compounds by metabolic chemical oxidation in the mitochondria within each cell.
Cellular respiration involves a series of enzyme-mediated reactions.
The equation below shows the complete oxidation of glucose. Oxygen is required for this energy-releasing process to occur. Release of energy during cellular respiration . Background Information A number of physical laws relating to gases are important to the understanding of how the apparatus that you will use in this exercise works. If temperature and pressure are kept constant, then the volume of the gas is directly proportional to the number of molecules of gas.
