5 Matching questions

  1. Photosynthesis
  2. Photosystem
  3. Stomata
  4. Photorespiration
  5. Calvin cycle
  1. a Transform light energy to chemical engergy stored in the bonds of sugar they make from carbon dioxide and water
  2. b Consists of Carbon fixation, reduction, release of G3P, and regeneration of RuBP. Using carbon from CO2, electrons from NADPH, and energy from ATP, the cycle constructs G#P, which is used to build glucose and other organic molecules
  3. c A metabolic pathway that consumes oxygen, releases carbon dioxide, generates no ATP
  4. d Tiny pores where carbon enters and oxygen exits
  5. e Consists of a number of light-harvesting complexes surrounding a reaction center complex

5 Multiple choice questions

  1. One molecule of G3P you see leaving the cycle is the net product of photosynthesis. A plant cell uses G3P to make glucose and other organic compounds
  2. A light-absorbing pigment in the chloroplasts that plays a central role in the chloroplasts
  3. Regeneration of RuBP
  4. Make the food for the organisms in the biosphere
  5. Contains a pair of chlorophyll a molecules and a molecule called the primary electron acceptor, which is capable of accepting electrons and becoming reduced

5 True/False questions

  1. C4 plantsAlternate modes of carbon fixation have evolved that save water without shutting down photosynthesis. Preced the Calvin cycle by first fixing CO2 into a four-carbon compound. Keeps its stromata mostly closed


  2. 2nd step of the Calvin cycleRelease of one molecule of G3P


  3. ReductionMake the food for the organisms in the biosphere


  4. Light reactionsAbsorb solar energy and convert it to chemical energy stored in ATP and NADPH


  5. Outputs of the light reactionsoxygen, ATP, NADPH
