Practice question
Question
If an enzyme is irreversibly inhibited, the inhibitor:
Explanation
Forms a strong covalent bond with the enzyme is the accurate response regarding enzymatic activity or regulation described in this question. Enzymes are biological catalysts that accelerate reactions by lowering activation energy through specific substrate binding and transition state stabilization. In the context of Enzyme Inhibition, Forms a strong covalent bond with the enzyme plays a specific catalytic or regulatory role determined by its active site configuration and mechanism of action. The other options (Forms a weak hydrogen bond with the enzyme, Can be removed by dialysis, and Can be reversed by increasing substrate concentration) are either different enzymes with distinct substrate specificities, act through different mechanisms, or are involved in separate metabolic pathways.
