5 Matching Questions

  1. Chlorophyll
  2. Light Reactions
  3. Carotenoid
  4. CAM pathway
  5. Primary Electron Acceptor
  1. a a class of pigments that are present in the thylakoid membrane of plants and that aid in photosynthesis
  2. b a green pigment that is present in most plant cells, that gives plants their characteristic green color, and that reacts with sunlight, carbon dioxide, and water to form carbohydrates
  3. c in chloroplasts, an acceptor of electrons lost from chlorophyll a; found in the thylakoid membrane
  4. d the initial reactions in photosynthesis, which are triggered by the absorbtion of light by photosystems I and II and include the passage of electrons along the electron transport chains, the production of NADPH and oxygen gas, and the synthesis of ATP through chemiosmosis
  5. e 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

5 Multiple Choice Questions

  1. 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
  2. the synthesis of organic compounds from carbon dioxide, such as in photosynthesis
  3. 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
  4. a biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP
  5. one of many openings in a leaf or a stem of a plant that enable gas exchange to occur
