Glucose, for example, is respired aerobically (with oxygen) in the human body thus -

C<sub>6</sub>H<sub>12</sub>O<sub>6</sub> + 6O<sub>2</sub> -> 6H<sub>2</sub>O + 6CO<sub>2</sub> + energy

C<sub>6</sub>H<sub>12</sub>O<sub>6</sub> -> 2C<sub>3</sub>H<sub>6</sub>O<sub>3</sub> + less energy

This energy is often used to turn [[ADP]] or [[AMP]] into [[ATP]], which is then used as a store of energy.
