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
