The process by which green plants use the energy of the sunlight to produce sugars (carbohydrates)
1) Light Dependent Reaction (produces energy) a. Reactions require direct involvement of light b. Occurs at chloroplasts i. Chlorophyll is main pigment of green plants ii. Absorbs blue/red regions of spectrum iii. Reflects green
c. Produce ATP d. Produce high energy electrons carried by NADP + e. Provide energy to make carbohydrates (sugars)!!!
Energy will be used to… Produce NADPH Split water Etc….
2) Light Independent Reaction (makes sugars) a. Does not directly involve light i. Can occur in the light or dark b. ATP and NADPH enter these reactions c. Convert energy from ATP and NADPH into a form that can be stored –Converts carbon dioxide and water into glucose
These reactions: Produces energy rich sugars Removes CO 2 from the atmosphere 6 turns = 1 sugar molecule
Formula for photosynthesis 6CO 2 + 6H 2 O C 6 H 12 O 6 + 6O 2 sunlight
Importance of photosynthesis Light energy converted to chemical energy
