Bio 1500 test 2
1. factors that allowed dragonflies to be so large: - high atmospheric oxygen levels enabled
large size
- predation
- birds evolved
2. Evidence that supports Clapham and Karr conclusion: - oxygen levels enabled large size
- oxygen levels have less correlation after the evolution of birds
3. wavelengths of light absorbed by chlorophyll: red, blue, and violet
4. light dependent reaction basic function: - atp synthesized
- NADPH generated
- water split apart in process, releasing O2 as a byproduct
5. light dependent reaction input and output: input: light, H2O, NADP+, ATP
output: NADPH, ATP, O2
6. light independent reaction basic function: energy from ATP and NADPH are used to build
glucose from CO2 and water (Calvin cycle)
1/4
, 7. light independent reaction input and output: input: CO2, NADPH, ATP
output: glyceraldehyde-3-phosphate
8. Why is O2 a by product of photosynthesis?: oxygen is a waste material because it is not involved
in the synthesis of food material (ie glucose)
9. ATP: - main transport form in cells
- immediate source of energy in cells
10. chemical changes that occur as ADP cycles to ATP, then back to ADP: hydrolysis:
consumes a water molecule
11. energetic changes that occur as ADP cycles to ATP, then back to ADP: energy is
released
12. processes that lead to Great Oxygen Event: - cyanobacteria evolved photosynthesis
- O2 produced as by product
13. how did the Earth look before the Great Oxygen Event?: - all organisms heterotrophic
prokaryotes
