Answer:
A: By breaking and reforming chemical bonds in the molecules
Explanation:
There is energy stored in chemical bonds between food molecules, called ATP. When chemical bonds are created, some energy is stored in those bonds. When one of these bonds are broken, the energy that was stored is released, and can then be used by your body. Your body then uses a different type of energy, called ADP, to reform the bonds, which then go on to become waste products.
