An experiment was conducted in order to determine the oxygen consumption in dry and soaked peas within two different temperatures of water. Cellular respiration is the release of energy by metabolic chemical oxidation in the mitochondria, (DeStefano 2016). The hypothesis was the germinating warm water peas would have the highest rate of oxygen consumption. Within this experiment, a twenty-one degree celsius bath and a six degree celsius bath were set up. Then, a one hundred mL graduated cylinder was filled with fifty mL of water. Twenty-five germinating peas were then placed inside. The amount of water displaced was then determined and recorded; and the peas were removed and placed on a paper towel. This procedure was repeated with glass beads…show more content…
Cellular respiration can be measured by the consumption of oxygen, the consumption of carbon dioxide, and the release of energy during cellular respiration. Within the experiment conducted, the relative volume of O2 consumed was measured into different temperatures within germinating and nongerminating peas, (DeStefano). Fluids and gas flow from regions of high-pressure to regions of low-pressure this carbon dioxide produced during cellular respiration will be removed by potassium hydroxide and will form a solid potassium carbonate. Due to the removal of carbon dioxide, the change in the volume of gas in the respirometer will be directly related to the amount of oxygen consumed. In this experiment using a respirometer, the scientists were able to measure the amount of oxygen being consumed in relation to how quickly the peas were respiring. Hypothesis If the germinating and dry peas are submerged in baths of water for twenty minutes, then the germinating peas will consume the most oxygen over dry peas. The warmer the temperature surrounding the vials, the faster the rate of oxygen consumption will be due to them requiring a more extensive output
