Cellular Respiration By- Gautham Giri Respiration Experiment #1 Lab Report I NTRODUCTION In this experiment, we worked with seeds that are living but dormant. A seed contains an embryo plant and a food supply surrounded by a seed coat. When the necessary conditions are met, germination occurs, and the rate of cellular respiration greatly increases. In this experiment, we measured how much oxygen gas is used up during cellular respiration. When plants respire, oxygen is needed to take the ATP from the organic compound. During respiration, plants need oxygen, whereas during photosynthesis they need CO 2 . We used three different controls to test the respiration on. We used germinating peas, dried peas, and beads. Cellular respiration is the release of energy from organic compounds by metabolic chemical oxidation in the mitochondria within each cell. The equation below shows the complete oxidation of glucose. Oxygen is required for this energy-releasing process to occur (Oxygen is taken in, and carbon dioxide that is produced during photosynthesis, is released). C 6 H 12 O 6 + 6O 2 -----> 6CO 2 + 6H 2 O Cellular respiration is most often described as the oxidation of glucose. Cellular respiration can be measured in three manners: the consumption of O 2 , production of CO 2 , and the release of energy during cellular respiration. Respiration is not breathing. In plants, it’s the release of energy from food. H YPOTHESIS Our hypothesis was that the germinating peas would do the most respiration, and therefore will be faster than the other two controls. We came up to this hypothesis because germinating peas are just going to grow, and they need a lot of energy. So, they need a lot of oxygen, and therefore more oxygen is
