5 Written questions

5 Matching questions

  1. primary electron acceptor
  2. CAM Plants
  3. C3 Plant
  4. photorespiration
  5. Photon
  1. a A plant that uses the Calvin cycle for the initial steps that incorporate CO2 into organic material, forming a three-carbon compound as the first stable intermediate.
  2. b a tiny particle or packet of light energy
  3. c in chloroplasts, an acceptor of electrons lost from chlorophyll a; found in the thylakoid membrane
  4. d A metabolic pathway that consumes oxygen, releases carbon dioxide, generates no ATP, and decreases photosynthetic output.
  5. e Store the organic acids made at night in vacuoles and use them for photosynthesis during the day when stomata are closed

5 Multiple choice questions

  1. reactions of photosynthesis that use energy from light to produce ATP and NADPH
  2. An enzyme that adds CO2 to phosphoenolpyruvate (PEP) to form oxaloacetate in C4 plants. It acts prior to photosynthesis.
  3. A photosynthetic pigment that participates directly in the light reactions, which convert solar energy to chemical energy.
  4. One of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P700 reaction-center chlorophyll.
  5. process by which plants use the sun's energy to convert water and carbon dioxide into sugars

5 True/False questions

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

          

  2. Chlorophyll balmost identical to chlorophyll a, but slightly different absorption spectra, yellow-green

          

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

          

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

          

  5. photosystem IIOne of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P700 reaction-center chlorophyll.
