VCE Unit 3 BIO: Enzymes

Enzymes belong to which family of biomacromolecules?

• Protein

• Carbohydrate

• Nucleic acid

• Lipids

Catabolic reactions involve...

• the break down of larger molecules and the release of energy

• the formation of larger molecules and absorption of energy

Anabolic reactions involve...

• the break down of larger molecules and the release of energy

• the formation of larger molecules and absorption of energy

The induced fit model differs to the lock and key model in that...

• The induced fit model states that the active site of the enzyme changes shape slight to fit the shape of the substrate

• The induced fit model states that the active site of the substrate changes shape slight to fit the shape of the enzyme

• The induced fit model states that the allosteric site of the enzyme changes shape slight to fit the shape of the substrate

• The induced fit model states that the allosteric site of the substrate changes shape slight to fit the shape of the enzyme

Inorganic molecules that complete the structure and ensure the functionality of an enzyme are referred to as

• Cofactors

• Coenzymes

Organic molecules that complete the structure and ensure the functionality of an enzyme and may become loaded during the reaction are referred to as

• Cofactors

• Coenzymes
