Enzymes
Before they can react, many molecules need to be destabilized. This state is typically achieved through

oxidizing the molecules by removing electrons
the input of a small amount of activation energy
changing the reaction from a biosynthetic to a catabolic pathway
changing the three-dimensional shape of the molecule
