Carbohydrates
Definition
Carbohydrates are organic compounds that serve as a major source of chemical energy for living organisms.
Formula / Key Relation
A simplified aerobic respiration equation is: `C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy` Glucose contains stored chemical energy. Cells release this energy through controlled biochemical reactions. Glucose: `C₆H₁₂O₆` Aerobic respiration: `C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy`

- Main role:
- ENERGY
- Glucose:
- `C₆H₁₂O₆`
- Respiration:
- Glucose + O₂
- → CO₂ + H₂O + energy
60-second revision
- Carbohydrates provide chemical energy, often after digestion into glucose that can be oxidised during respiration.
