6. 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

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

  • Thylakoid space
  • Stroma
  • Thylakoid membrane

8. 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

9. What are the 3 most common limiting factors of photosynthesis?

  • Temperature, light intensity and carbon dioxide concentration
  • Temperature, soil pH and water availability
  • Light intensity, water availability and carbon dioxide concentration
  • Carbon dioxide concentration, soil pH and temperature

10. When the electrons pass down the ECT, what do the electrons lose and why?

  • Oxygen because they are being reduced
  • Energy because each carrier is at a lower energy level than the previous one in the chain
  • Nothing

11. What is TP then converted into?

  • Water
  • Rubisco
  • Organic substances or regenerated into RuBP
  • Organic substances and oxygen

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

  • Mitochondria
  • Thylakoids
  • Stroma
  • Cytoplasm

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

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

14. What is the chemiosmotic theory?

  • Protons are pumped into the thylakoid space, water moves into the thylakoid space
  • 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
  • Stroma has high conc. of protons, protons transported into thylakoid space via ATP synthase channel

15. Where does photosynthesis take place?

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