  1. Carbon Fixation
  2. Stoma
  3. CAM pathway
  4. Electron Transport Chain
  5. Photosynthesis
  1. a a series of molecules, found in the inner membranes of mitochondria and chloroplasts, through which electrons pass in a process that causes protons to build up on one side of the membrane
  2. b a water-conserving, carbon-fixing process; ____ plants take in carbon at night and fix it into various organic compounds and release it during the day
  3. c one of many openings in a leaf or a stem of a plant that enable gas exchange to occur
  4. d the process by which plants, algae, and some bacteria use sunlight, carbon dioxide and water to to produce carbohydrates and oxygen
  5. e the synthesis of organic compounds from carbon dioxide, such as in photosynthesis

5 Multiple choice questions

  1. in the thylakoid membranes of chloroplasts, a cluster of chlorophyll and other pigment molecules that harvest light energy for the light reactions of photosynthesis
  2. in chloroplasts and mitochondria, a process in which the movement of protons down their concentration gradient across a membrane is coupled to the synthesis of ATP
  3. a biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP
  4. a membrane system found within chloroplasts that contains the components for photosynthesis
  5. an organism that produces its own nutrients from inorganic substances or from the environment instead of consuming other organisms

5 True/False questions

  2. Heterotrophan organism that obtains organic food molecules by eating other organisms or their byproducts and that cannot synthesize organic compounds from inorganic materials


  3. C4 pathwaya carbon-fixing process in which carbon dioxide is bound to a compound to form a four-carbon intermediate
