1. Two Stages of Photosynthesis:
1) the LIGHT REACTIONS
2) the CALVIN CYCLE
(a.k.a. the light-independent
reactions)

2. LIGHT DEPENDENT REACTIONS:
• convert solar energy  chemical energy
• light is absorbed by chlorophyll and drives a transfer of electrons and H from water to an acceptor called: NADP+
• water is split and O2 is produced as a waste product
• NADP+ is reduced to NADPH…ALSO, ATP is generated via phosphorylation of ADP

4. LIGHT INDEPENDENT REACTIONS (Calvin Cycle):
• CO2 from air is incorporated into organic molecules by carbon fixation
• NADPH and ATP from the light reactions power the production of sugar

5. Locations of the Photosynthesis Reactions:
• Light dependent reactions occur in the THYLAKOIDS
• Light independent reactions occurs in the STROMA

6. Where is chlorophyll located?
Stroma
Granum
Grana
Thylakoid membrane

7. The oxygen that a plant releases comes from what reactant?
Carbon dioxide
Water
Glucose
Sunlight

8. The energy that is stored in glucose originally came from _____.
ATP & NADPH
Pyruvate

9. The ATP that is needed in the Light Independent Reactions needs to be produced where?
