Noncompetitive inhibition of enzymes:

Question

Quizplus · Accepted Answer

Noncompetitive inhibition of enzymes occurs when a substance binds to an enzyme at a site away from the active site, which alters the shape of the active site and prevents the substrate from binding. This type of inhibition is different from competitive inhibition, where a substance binds to the active site and directly competes with the substrate for binding. Noncompetitive inhibitors do not necessarily affect the catalytic activity of the enzyme but instead reduce its efficiency by changing its shape.
