Glucose (C6H12O6) is an example of a hydrocarbon and a simple sugar. The most common reaction of glucose with oxygen is through the combustion reaction. Combustion reaction is a type of reaction wherein a substance reacts rapidly with oxygen and releases energy.  The energy is observed as heat and light.  The general equation for the combustion of hydrocarbon is:

Hydrocarbon + oxygen  —>> carbon dioxide + water

Now, for the combustion of glucose, the chemical equation will be

C6H12O6 +   O2 --->  CO2 +  H2O

The equation needs to be balanced as:

C6H12O6 +  6O2 --->  6CO2 + 6H2O
