Other questions in this quiz

2. In the light-indepedent reaction (Calvin cycle) Ribulose biphospate combines with CO2, aided by enzyme action. What is the product of this?

  • Glycerate 3 phospate
  • Phosporylated glucose
  • Triose phospate
  • ADP and Pi

3. Where does the light-dependent reaction take place?

  • In the lower mesophyll layer only
  • In the thylakoid membrane of the chloroplast
  • In the stroma
  • In the chloroplast membrane

4. Why is the rate of photosynthesis not equal to the net uptake of CO2 by a plant?

  • Because CO2 is used only in the light-indepedent reaction
  • Because some CO2 produced in respiration is used for photosynthesis
  • Because the rate of photosynthesis increases with temperature
  • Because venus flytraps are carnivores

5. Where does the light-independent reaction take place?

  • In the stomata
  • In the thylakoid membrane of the chloroplast
  • In the stroma
  • In the chloroplast membrane
