Cellular Respiration Lab Walkthrough

Mr. Anderson guides students through AP Biology Lab 5, focusing on cellular respiration. The lab uses a respirometer to measure the respiration rate of worms and peas by tracking oxygen consumption. The experiment involves setting up a respirometer with potassium hydroxide to absorb carbon dioxide, allowing for accurate measurement of oxygen use. Data is collected over time, and results are analyzed to compare respiration rates of germinating peas, non-germinating peas, and worms. The lab demonstrates the principles of cellular respiration and the importance of controls in scientific experiments.
