Anabolic and Catabolic Enzymes

Anabolic Catabolic

Anabolism refers to chemical reactions in

which simpler substances are

combined to form more complex

molecules.

Catabolism refers to chemical reactions in

which complex molecules are broken

down into simpler substances.

Anabolic reactions

usually require energy.

Anabolic reactions build new molecules and/or store energy.

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
