Introduction: In the experiment we were testing the rate of cellular respiration in germinated and ungerminated peas. Cellular respiration is when chemical energy is released and changed into ATP, which creates energy.
Procedure: To begin the experiment we had to measure the room temperature using a thermometer and then record the temperature in table 1. Then we gathered 23 germinated peas and placed them into the respiration chamber. Once the CO2 shaft was in place we let the peas sit for a minute before we began to collect the data, which lasted for 10 minutes. Once a lll the data was collected a graph of CO2 gas vs. time was displayed. After that we soaked the germinated peas in ice water and then repeated the same process and graphed the data.
Discussion/Conclusion: In our experiment, our graph showed an inverse relationship between the amount of carbon dioxide and oxygen in our container. Oxygen went down as time increased while the amount of carbon dioxide increased as time increased. This showcases cell respiration. The germinating seeds used the oxygen to oxidize the sugars inside and create more ATP. They did this in order to continue germinating and allow themselves to grow. The only way to do this is with energy. As a result, as the seeds continued to make more and more energy, the amount of oxygen in the container decreased. Therefore, the amount of carbon dioxide increased considering the carbons of the sugar molecules were released as carbon dioxide.
When we submerged our seeds in water and later put them in our container, we got the same inverse relationship. However, the amount of oxygen depleted and carbon dioxide gained did not occur at as rapid of a speed. This is because in cellular respiration, the oxygen used is reduced to water. Therefore, the seeds were already covered in water, making it harder for them to receive the oxygen they needed to create more energy. This left more oxygen in the container and did not allow carbon dioxide to be created as quickly as when they were dry.
The experiment's results could have been tampered by us not closing the container fully. Thus, it was an open system and changes in temperature could have affected it as well as more oxygen rushing in, making our graph constant, with the amount of oxygen in the container staying the same. When a temperature is warmer, cellular respiration occurs at a faster rate.
