1. Purpose
    • to convert solar energy to usable chemical energy and store that energy in sugar molecules
    • provides organisms with organic carbon
  2. Photosynthesis is a __, not a __.
    • biochemical process
    • chemcial reaction
  3. In brief, it links __ and __ using energy from __ that has temporarily been stored in two differnet high energy compounds.
    • carbon dioxide
    • water
    • light
  4. The overall effect of photosynthesis is the reverse of __.
    aerobic cell resp
  5. Which molecule is energy poor and which is energy rich
    • co2 is energy poor
    • glucose is energy rich
  6. Phyotosynthesis is the ultimate energy source for almost all organisms. Those organisms that cannot use sunlight directly must rely on photosynthetic organisms directly or indirectly for a source of energy and organic carbon.
  7. In addition to the major product of photosynthesis, __, __ is also produced. Photosynthesis is the source of __ that is used in CR
    • energy rich glucose
    • O2
    • O2 in the air
  8. The entire process of phtosynthesis, starting with CO2 and H2o and ending with glucose, occurs in two main parts or phases
    • photophosphorylation (light reactions)
    • Calvin Cycle (dark reactions)
  9. Purpose of photophosphorylation?
    to trap light energy, convert it to chemical energy and store it temporarily in molecules
  10. Purpose of Calvin cycle
    to use chemical energy stored in ATP and NADPH produced in photophosphorylation to reduce CO2 to sugar, enabling organism to store that energy long-term
  11. Therefore, __ and__ link the light and dark reactions.
    • ATP
    • NADPH
  12. Both stages of photosynthesis occur in __.
