Biochemistry classification: Oxyreductases, transferases, hydrolases, lyases, isomerases, and ligases belong to which biomolecular class? Context: These categories are defined by the reactions they catalyze in metabolism. Choose the correct overarching class.

Given data

• Six named classes correspond to reaction types in metabolism.

Concept / ApproachThe International Union of Biochemistry and Molecular Biology (IUBMB) classifies enzymes into six major classes by catalytic function: oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases.

Why others are incorrectHormones and vitamins regulate or support metabolism but are not classified by these catalytic categories.

Final AnswerEnzymes.
