B) always non-covalently
C) either covalently or non-covalently

Question

Quizplus · Accepted Answer

Cofactors can be bound to their enzymes either covalently or non-covalently. Some cofactors, like heme groups in cytochromes, are covalently bound to the protein structure, while others bind through non-covalent interactions, such as metal ions or coenzymes like NAD+ or FAD. The choice of whether to bind covalently or non-covalently depends on the chemical properties of the cofactor and its interaction with the enzyme's active site.
