5 Matching questions

  1. spectrophotometer
  2. Chlorophyll a
  3. Carbon fixation
  4. Thylakoid
  5. Photon
  1. a A photosynthetic pigment that participates directly in the light reactions, which convert solar energy to chemical energy.
  2. b a tiny particle or packet of light energy
  3. c A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.
  4. d the synthesis of organic compounds from carbon dioxide, such as in photosynthesis
  5. e An instrument that measures the proportions of light of different wavelengths absorbed and transmitted by a pigment solution.

5 Multiple choice questions

  1. A route of electron flow during the light reactions of photosynthesis that involves only photosystem I and that produces ATP but not NADPH or oxygen
  2. a 3 carbon sugar; for each CO2 are formed in the Calvin cycle; 1 leaves to be used in the cell, 5 are use for regeneration of RuBP
  3. An enzyme that adds CO2 to phosphoenolpyruvate (PEP) to form oxaloacetate in C4 plants. It acts prior to photosynthesis.
  4. type of plant that minimizes photorespiration by fixing carbon twice, using a C4 pathway in addition to the Calvin-Benson Cycle.
  5. Store the organic acids made at night in vacuoles and use them for photosynthesis during the day when stomata are closed

5 True/False questions

  1. Rubiscoenzyme that converts inorganic carbon dioxide molecules into organic molecules during the final step of the calvin cycle

          

  2. wavelengthtype of plant that minimizes photorespiration by fixing carbon twice, using a C4 pathway in addition to the Calvin-Benson Cycle.

          

  3. photorespirationThe process of generating ATP from ADP and phosphate by means of a proton-motive force generated by the thylakoid membrane of the chloroplast during the light reactions of photosynthesis.

          

  4. Calvin Cyclegreen pigment in plants that absorbs light energy used to carry out photosynthesis

          

  5. MesophyllThe ground tissue of a leaf, sandwiched between the upper and lower epidermis and specialized for photosynthesis.
