Detailed explanation-1: -Answer and Explanation: Catabolism is to Exergonic: as Anabolism is to Endergonic.

Detailed explanation-2: -Catabolic reactions give out energy. They are exergonic. In a catabolic reaction large molecules are broken down into smaller ones.

Detailed explanation-3: -The building of complex molecules, such as sugars, from simpler ones is an anabolic process and is endergonic. On the other hand, the catabolic process, such as the breaking down of sugar into simpler molecules is generally exergonic.

Detailed explanation-4: -Endergonic reactions in organisms are called anabolic reactions. These reactions absorb energy and build bigger molecules from smaller ones. An example of an anabolic reaction is the joining of amino acids to form a protein.
