- **Chemiosmosis:** ATP production linked to proton gradient.
#### Page 12: Photosynthesis
- **Overall Reaction:** 6CO₂ + 6H₂O + light energy = C₆H₁₂O₆ + 6O₂.
- **Stages:**
- Light-dependent reactions: Convert light energy into chemical energy (ATP, NADPH).
- Light-independent reactions (Calvin Cycle): Use ATP and NADPH to synthesize glucose.
#### Page 13: Cell Signaling
