5 Matching questions

  1. Autotrophs
  2. Light reactions
  3. C3 plants
  4. Producers
  5. Stroma
  1. a Make the food for the organisms in the biosphere
  2. b A thick fluid that is enclosed by the two membranes of the chloroplast
  3. c Organisms that make their own food and thus sustain themselves without consuming organic molecules derived from any other organisms
  4. d Absorb solar energy and convert it to chemical energy stored in ATP and NADPH
  5. e First organic compound produced is the three-carbon compound 3-PGA.Common and widely distributed; they include soy beans, oats, wheat and rice.

5 Multiple choice questions

  1. A metabolic pathway that consumes oxygen, releases carbon dioxide, generates no ATP
  2. Two 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
  3. Organisms that produce organic molecules from inorganic molecules using the energy of light
  4. Consists of a number of light-harvesting complexes surrounding a reaction center complex
  5. The distance between the crest of two adjacent waves

5 True/False questions

  1. Carbon fixationRubisco combines CO2 with a five-carbon sugar called ribulose bisphosphate (RuBP). The unstable product splits into two molecules of the three-carbon organic acid, 3-phosphoglyceric acid (3-PGA). For three CO3 entering, six 3-PGA result

          

  2. ThylakoidsInterconnected membranous sacs suspended in the stroma

          

  3. Inputs of the Calvin cycleCO2

          

  4. C4 plantsFirst organic compound produced is the three-carbon compound 3-PGA.Common and widely distributed; they include soy beans, oats, wheat and rice.

          

  5. Outputs of the light reactionsEnergy from light, water, ADP + P, NADP+
