(a)
Interpretation:
The class of enzymes to which the enzyme involved in the given reaction belongs 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:
- 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.

- For each pair of biomolecules, identify the type of reaction (oxidation‑reduction, hydrolysis, isomerization, group transfer, or internal rearrangement) required to convert the first molecule to the second. In each case, indicate the general type of enzyme and cofactor(s) or reactants required, and any other products that would result A(n) (hydrolysis, oxidation reduction, group transfer, isomerization, internal rearrangment) reaction converts L‑leucine to D‑leucine. This reaction is catalyzed by a(n) (dehydrogenase, isomerase, kinase, protease).arrow_forwardIdris has successfully extracted enzymatic proteins from the fish viscera (intestines and stomach).
