6. A photosynthetic pigment is:

  • Molecules that only absorb one certain wavelength
  • They don't absorb green light
  • Molecules that absorb certain wavelengths whilst reflecting others
  • Molecules that reflect wavelengths

7. What effect does very high temperature have on the rate of photosynthesis?

  • Greater stress for the plant
  • Active site of rubisco will become denatured so no longer able to accept CO2
  • All of the above
  • Enzymes denature
  • More water loss from stomata

8. Light independent stage takes place in the

  • Thylakoid
  • Stroma
  • Chlorophyll
  • Grana

9. Non-cyclic photophosphorylation...

  • Uses only photosystem II (p680)
  • Uses both photosystems
  • Uses only photosystem I (p700)
  • Does involve using a photosystem

10. What causes the light dependent stage to stop because GP cannot be converted into TP?

  • Amount of carbon dioxide
  • Light intensity
  • Light
  • Amount of light

11. GP can be used to...

  • Form fatty acids and amino acids
  • Make fats
  • Form glycerol
  • Make cellulose and starch

12. Why are photosynthetic pigments arranged in a funnel shape?

  • Provide large surface area for electron carriers
  • To make a photosystem
  • To maximize light absorption and capture as much light as possible
  • To form an antenna complex.

13. Why is the equation that summaries photosynthesis, over-simplified?

  • Does not show enzymes used in the reactions e.g. Rubisco
  • All of the below
  • Does not account of intermediate processes used such as Calvin cycle
  • Does not show that ATP/energy is another product

14. Is Krebs cycle a part of photosynthesis?

  • Maybe
  • No
  • Yes

15. What is the role of water in the light-dependent stage?

  • Photolysis
  • Source of reduced NADP
  • Keeps plant turgid
  • Make oxygen, to be released in the atmosphere
