What is the difference between catabolic and anabolic reactions?

Catabolic and anabolic reactions are metabolic processes. Both the capture and use of energy by organisms involves a series of thousands of reactions (what we call metabolism). A catabolic reaction is one that breaks down large molecules to produce energy; for example, digestion is a catabolic reaction. An anabolic reaction is one that involves creating large molecules out of smaller molecules, for example, when your body makes fat out of the extra nutrients you eat.
