1. 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
1 of 15

Other questions in this quiz

2. 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

3. 'The rate of photosynthesis is affected by the factor whose level is at the least favourable value' this is called the...

  • stopping factor
  • least favourable factor
  • limiting factor
  • limited factor

4. The products of the photolysis (splitting) of water are...

  • O2, H+ and a neutron
  • H+ and an electron
  • O2, H+ and an electron
  • OH-, H+

5. In the calvin cycle, some of the Triose Phospate created is converted into glucose. What is NOT a possible use of the glucose produced?

  • Making proteins
  • Nitrification in roots
  • Conversion into starch for storage
  • Use in respiration
