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
- 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
11. What is TP then converted into?
- Organic substances or regenerated into RuBP
- Organic substances and oxygen
12. Where does the Light-Dependent reaction take place?
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
