5 Matching questions

  1. G3P
  2. photosystem II
  3. Carbon fixation
  4. Thylakoid
  5. photosynthesis
  1. a process by which plants use the sun's energy to convert water and carbon dioxide into sugars
  2. b the synthesis of organic compounds from carbon dioxide, such as in photosynthesis
  3. c A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.
  4. d 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
  5. e One of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P680 reaction-center chlorophyll.

5 Multiple choice questions

  1. a tiny particle or packet of light energy
  2. almost identical to chlorophyll a, but slightly different absorption spectra, yellow-green
  3. An instrument that measures the proportions of light of different wavelengths absorbed and transmitted by a pigment solution.
  4. one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules
  5. The distance between crests of electromagnetic waves.

5 True/False questions

  1. primary electron acceptorin chloroplasts, an acceptor of electrons lost from chlorophyll a; found in the thylakoid membrane

          

  2. PEP Carboxylaseyellow or orange pigment that serves as an accessory to chlorophyll in photosynthesis

          

  3. Autotrophorganism that obtains energy from the foods it consumes; also called a consumer

          

  4. Cyclic electron flowA route of electron flow during the light reactions of photosynthesis that involves only photosystem I and that produces ATP but not NADPH or oxygen

          

  5. photophosphorylationA metabolic pathway that consumes oxygen, releases carbon dioxide, generates no ATP, and decreases photosynthetic output.
