(a)
Interpretation:
The class of enzyme which would catalyse the given reaction should be determined.
Concept introduction:
Enzyme:
- It is a protein or a molecule which can act as a catalyst for a biological reaction.
- Does not affect the equilibrium point of the reaction.
- Active site of the enzyme is the region where the reaction takes place.
- Enzyme’s activity can be specific which means the activity is limited to a certain substrate and a certain type of reaction and it is referred to as specificity of the enzyme.
Classification of enzymes:
Enzymes can be classified into six categories according to the reaction they catalyse
- Oxidoreductases: Used to catalyse
oxidation-reduction reactions . - Transferases: Used to catalyse transfer of a functional group from one molecule to another.
- Hydrolases: Used to break a large molecule into smaller ones using water.
- Isomerases: Used to catalyse isomerization reactions.
- Lyases: Used to catalyse addition or removal of a small molecule.
- Ligases: Used to catalyse the bonding of two substrate molecules.
