Verified step by step guidance

Understand the role of each enzyme class: Oxidoreductases are involved in oxidation-reduction reactions, Hydrolases catalyze the hydrolysis of various bonds, Lyases break bonds by means other than hydrolysis and oxidation, and Isomerases catalyze the rearrangement of atoms within a molecule.

Identify the type of reaction: Converting a cis-fatty acid to a trans-fatty acid involves rearranging the structure of the molecule without adding or removing atoms, which is a structural rearrangement.

Determine which enzyme class is responsible for structural rearrangements: Isomerases are the enzymes that catalyze the rearrangement of atoms within a molecule, making them responsible for converting cis to trans configurations.

Consider the specific reaction: The conversion of a cis-fatty acid to a trans-fatty acid is a type of isomerization reaction, where the spatial arrangement of the atoms is changed.

Conclude that the enzyme class required for this conversion is Isomerase, as it facilitates the rearrangement of the molecular structure without altering the molecular formula.
