The better analogy would be like a burning fire. Burning wood (cellulose) is a molecular rearrangement:
C6H12O6 + 6*O2 --> 6*CO2 + 6*H2O
It turns out that the electrons are much happier (lower energy orbitals) residing in carbon dioxide or water rather than cellulose or molecular oxygen, so a good deal of energy is released. There are also rearrangements that work the other way, such as the construction of cellulose by plants from carbon dioxide and water, which requires quite a hefty energy input (more than you get back by burning the cellulose--that's called the Second Law of Thermodynamics).

You can't even break even.
You can't get out of the game.
