AP Biology Lab 5: Cellular Respiration

Mr. Anderson guides students through an AP biology lab on cellular respiration, focusing on measuring respiration rates using a respirometer. The lab involves using worms and peas to observe oxygen consumption and carbon dioxide production. Key steps include glycolysis, the Krebs cycle, and the electron transport chain. The experiment uses potassium hydroxide to absorb CO2, allowing for accurate measurement of oxygen consumption. Data analysis reveals that germinating peas have the highest respiration rate, followed by worms and non-germinating peas.
