📖 Physical Concept & Comprehensive Explanation
Photosynthesis drives primary ecological production. Chloroplasts synthesize carbohydrates from water and CO2 under sunlight. Light-dependent reactions produce ATP and NADPH in thylakoids, which drive the Calvin cycle in the stroma.
🎯 High-Yield Revision Points
- ✓Net reaction: 6CO2 + 12H2O -> C6H12O6 + 6O2 + 6H2O.
- ✓Takes place within leaf mesophyll chloroplasts.
- ✓Releases breathable oxygen as an essential metabolic byproduct.
