Which of the following strategies of enzymatic inhibition is used by noncompetitive inhibitors?
Correct answer: D. Bind to allosteric site to cause a conformational shift in the enzyme
- A. Bind to substrate so that it cannot bind to the active site
- B. Target the enzyme for destruction using a protease
- C. Bind to the active site and prevent substrate from binding
- D. Bind to allosteric site to cause a conformational shift in the enzyme
Explanation
As summed up by the diagram, the binding of noncompetitive inhibitor causes alteration in the bonding of active site, as a result substrate can no longer bind to the ative site. Inhibition occurs as product not made.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
