Summary of key differences between photosynthesis and respiration:
Photosynthesis
- Energy stored in sugar molecules
- Carbon dioxide and water used
- Increases weight
- Requires light
- Occurs in chlorophyll
- In green organisms, produces oxygen
- With light energy, produces ATP
Respiration
- Energy released from sugar molecules
- Carbon dioxide and water released
- Decreases weight
- Can occur in light or darkness
- Occurs in all living cells
- Uses oxygen (aerobic respiration)
- With energy released from sugar, produces ATP.
