5 Multiple choice questions

  1. Rubisco 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. Absorb solar energy and convert it to chemical energy stored in ATP and NADPH
  3. These species are adapted to very dry climates. Pineapples, Cacti and succulent plants
  4. Stacks of thylakoids
  5. Organisms that produce organic molecules from inorganic molecules using the energy of light

5 True/False questions

  1. Outputs of the Calvin cycleSugar, NADP+, ADP + P


  2. 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


  3. ChlorophyllA light-absorbing pigment in the chloroplasts that plays a central role in the chloroplasts


  4. 4th step of the Calvin cycleRelease of one molecule of G3P


  5. 2nd step of the Calvin cycleReducation
