5 Matching questions

  1. Primary Electron Acceptor
  2. Light Reactions
  3. Heterotroph
  4. CAM pathway
  5. C4 pathway
  1. a a carbon-fixing process in which carbon dioxide is bound to a compound to form a four-carbon intermediate
  2. b an organism that obtains organic food molecules by eating other organisms or their byproducts and that cannot synthesize organic compounds from inorganic materials
  3. c 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
  4. d in chloroplasts, an acceptor of electrons lost from chlorophyll a; found in the thylakoid membrane
  5. e 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 Multiple choice questions

  1. the synthesis of organic compounds from carbon dioxide, such as in photosynthesis
  2. one of many openings in a leaf or a stem of a plant that enable gas exchange to occur
  3. in the thylakoid membranes of chloroplasts, a cluster of chlorophyll and other pigment molecules that harvest light energy for the light reactions of photosynthesis
  4. an organism that produces its own nutrients from inorganic substances or from the environment instead of consuming other organisms
  5. a stack of thylakoids in a chloroplast

5 True/False questions

  1. Thylakoida membrane system found within chloroplasts that contains the components for photosynthesis

          

  2. Carotenoida membrane system found within chloroplasts that contains the components for photosynthesis

          

  3. Chemiosmosisin 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

          

  4. Chloroplasta 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

          

  5. Calvin Cyclea biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP
