Anabolic and Catabolic Enzymes Anabolism refers to chemical reactions in which simpler substances are combined to form more complex molecules. Anabolism refers to chemical reactions in which simpler substances are combined to form more complex molecules.

Anabolic reactions build new molecules and/or store energy. Anabolic reactions usually require energy. Anabolic reactions build new molecules and/or store energy.

The energy of catabolic reactions is used to drive anabolic reactions. Catabolic reactions usually release energy that is used to drive chemical reactions. The energy of catabolic reactions is used to drive anabolic reactions.

Enzymes and DNA Strands of DNA are held together by hydrogen bonds. During the replication of DNA, these bonds are broken by an enzyme called DNA helicase
