Investigating respiration. Objectives Recall how temperature affects the rate of enzyme controlled reactions. Analyse results from an investigation Explain how a manometer works. Factors that affect respiration.
Come up with a list of factors that could affect the rate of respiration. For each one try to give an explanation.
2. Temperature-Respiration is enzyme controlled.
3. pH-Respiration is enzyme controlled.
4. Enzyme inhibitors.
5. Problems with mitochondria.
-Used to measure the rate of respiration.
-Measures the volume of oxygen used up by displacing a liquid.
Volume of oxygen can then be calculated by using the diameter of the capillary tube.
-Soda lime is used to absorb carbon dioxide produced. This ensures that the liquid will only move due to the depletion of oxygen.
