6. What is the chemiosmotic theory?

  • Thylakoid space has high conc. of protons, protons transported into stroma through ATP synthase channel, producing ATP
  • Water is transported into the stroma through the ATP synthase channel, producing ATP
  • Protons are pumped into the thylakoid space, water moves into the thylakoid space
  • Stroma has high conc. of protons, protons transported into thylakoid space via ATP synthase channel

7. When chlorophyll absorbs light energy, it decreases the energy of a pair of electrons

  • False
  • True

8. Where does the Light-Independent Reaction take place?

  • Stroma
  • Thylakoid membrane
  • Thylakoid space

9. Where does the Light-Dependent reaction take place?

  • Mitochondria
  • Cytoplasm
  • Thylakoids
  • Stroma

10. Where does photosynthesis take place?

  • In the nucleus in the leaf
  • In the mitochondria in the leaf
  • In the chloroplasts in the leaf
  • In the chloroplasts in the roots

11. What is the equation for photosynthesis?

  • Carbon dioxide + glucose = oxygen + water
  • Carbon dioxide + water = glucose + oxygen
  • Glucose + water = oxygen + carbon dioxide
  • Glucose + oxygen = carbon dioxide + water

12. How can the rate of photosynthesis be measured?

  • By measuring the volume of oxygen produced
  • By calculating how much oxygen has been taken up
  • By calculating how much carbon dioxide has been taken up
  • By measuring how much water has been produced

13. What is the photolysis of water?

  • When water is broken down by light energy to produce protons, electrons and oxygen
  • When water is broken down by light energy to produce oxygen and protons
  • When water is broken down by light energy to produce protons and electrons
  • When water is broken down by light energy to produce electrons and oxygen

14. What are the two main products of the LDR?

  • oxygen and reduced NADP
  • Reduced FADP and ATP
  • Reduced NADP and ATP
  • ATP and oxygen

15. What adaptations of the leaf make it suitable for photosynthesis?

  • Large surface area, thin, non-overlapping, numerous stomata, air spaces in mesophyll, xylem
  • Small surface area, thick, over-lapping, few stomata, no air spaces in mesophyll, no xylem
