1. Catabolism. 1  The process by which complex molecules are broken down into smaller, simpler molecules. 2  Also known as: destructive metabolism. 3  Word derivation: Cata: down.  Two key results of catabolism: Stored energy is released.
As you said, it's true that breaking bonds always absorbs energy. But breaking bonds is just halfway through for a chemical reaction. Forming new ones releases energy. The difference within determines a chemical reaction endothermic or exothermic. For ATP hydrolysis, the bonds within an ATP and a water molecule break, which absorbs energy, as you might think. Then the new bonds formation to form an ADP and a phosphate releases a lot of energy.
