  5. 2nd step of the Calvin cycle
  1. a Consists of a number of light-harvesting complexes surrounding a reaction center complex
  2. b Alternate 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
  3. c Reducation
  4. d Transform light energy to chemical engergy stored in the bonds of sugar they make from carbon dioxide and water

5 Multiple choice questions

  1. Carbon fixation
  2. Organisms that produce organic molecules from inorganic molecules using the energy of light
  3. Sugar, NADP+, ADP + P
  4. Energy from light, water, ADP + P, NADP+
  5. Release of one molecule of G3P

5 True/False questions

  1. ReductionMake the food for the organisms in the biosphere


  2. ThylakoidsFirst organic compound produced is the three-carbon compound 3-PGA.Common and widely distributed; they include soy beans, oats, wheat and rice.


  3. ProducersTwo chemical reactions consume energy from six molecules of ATP and oxidize six molecules of NADPH. Six molecules of 3-PGA are reduced, producing six molecules of G3P


  4. MesophyllThe green tissue in the interior of the leaf


  5. PhotonStacks of thylakoids
