2. n CO n H2O
+ photons
→ (CH2O)n + nO2
carbon dioxide + water
+ light
→ carbohydrate + oxygen
enzyme zymase
→ 2 C2H5OH CO2
(CH2O)6
carbohydrate
→ alcohol + CO2

6. CO2 + H2O → C6H6OH C6H12O6 + Zymase → 2 C2H5OH + 2 CO2
2n CO2 + 2n H2O + photons → 2(CH2O)n + 2n O2
carbon dioxide + water + light energy → carbohydrate + oxygen
Other processes substitute other compounds (such as arsenite) for w
CO2 + H2O → C6H6OH
C6H12O6 + Zymase → 2 C2H5OH + 2 CO2
