11B - 1 Experiment 11B Cellular Respiration Cellular respiration refers to the process of converting the chemical energy of organic molecules into a form immediately usable by organisms. Glucose may be oxidized completely if sufficient oxygen is available by the following equation: C 6 H 12 O 6 + 6 O 2 (g) ← → 6 H 2 O + 6 CO 2 (g) + energy All organisms, including plants and animals, oxidize glucose for energy. Often, this energy is used to convert ADP and phosphate into ATP. It is known that peas undergo cellular respiration during germination. Do peas undergo cellular respiration before germination? The results of this experiment will verify that germinated peas do respire. Using your collected data, you will be able to answer the question concerning respiration and non-germinated peas. Using the CO 2 Gas Sensor, you will monitor the carbon dioxide produced by peas during cellular respiration. Both germinated and non-germinated peas will be tested. Additionally, cellular respiration of germinated peas at two different temperatures will be tested. 1.
