- solar energy is trapped and stored as chemical energy in the bonds of sugar (glucose)
- endergonic reaction
- energy+carbon dioxide+water= glucose+oxygen
- two processes= light reactions and calvin cycle
- "photo"= capturing sunlight
- "synthesis"= refers to making glucose
- organelles with a double membrane enclosing a fluid; FLUID; like cytoplasm
- Calvin Cycle occurs here!
- embedded in the stroma; disk-shaped membranous sacs
- light-dependent reaction of photosynthesis
- chlorophyll captures sunlight energy and converts some of it into chemical energy
- stores in the energy-carrying molecules ATP and NADPH
plants have evolved to avoid photorespiration; two types:
1. C4 Pathway= uses special mesophyll and bundle sheath cells to minimize photorespiration (dry environment)
2. CAM= performs different activities based on the time
these plants can be subject to photorespiration during harsh conditions
