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?
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
