Chemical Energy
Captions available
The idea
Chemical energy is potential energy stored in a molecule's chemical bonds, released when those bonds break.
In practice
The bonds in a glucose molecule release chemical energy when a cell breaks them apart during catabolism.
Where people slip
Breaking a bond releases energy only when that bond stored more energy than the bonds that replace it.
