Verified step by step guidance

Begin by understanding the term 'metabolism', which encompasses all chemical reactions in the body that maintain life. It includes both building up and breaking down processes.

Recognize that 'anabolism' refers to the metabolic pathways that construct molecules from smaller units, typically requiring energy. It is the opposite of the process we are looking for.

Identify 'catabolism' as the metabolic process that breaks down large molecules into smaller units, releasing energy. This is the process that specifically describes the breakdown of molecules.

Consider 'dehydration' in the context of metabolic processes. Dehydration synthesis is a type of anabolic reaction where water is removed to join molecules together, not break them down.

Conclude that the term 'catabolism' is the correct answer, as it specifically describes the breakdown of large molecules into smaller ones, releasing energy in the process.
