This is the burning of glucose to release lots of energy by reacting with oxygen:
Glucose + oxygen carbon dioxide + water
C6H12O6 + 6H2O 6CO2 + 6H2O
This is the breakdown of glucose in the absence of oxygen, producing only a small amount of energy.
Glucose ethanol + carbon dioxide
C6H12O6 2C2H6O + 2CO2
Glucose lactic acid
