Catabolic reactions give out energy. They are exergonic. In a catabolic reaction large molecules are broken down into smaller ones. For example, the reverse of the condensation reactions described above, i.e. hydrolysis reactions, are catabolic.
Catabolism is the breaking apart of molecules to smaller molecules to release energy. An example of a catabolic reaction is digestion and cellular respiration where you break apart sugars and fats for energy.Hydrolysis is the way in which this is done and it is basically the reverse of a dehydration reaction.Breaking down a protein into amino acids or a triglyceride into fatty acids or a disaccharide into monosaccharides are all hydrolysis or catabolic reactions.atabolism is the breaking apart of molecules to smaller molecules to release energy.
