A compound that binds to the surface of an enzyme, and changes its shape so that a substrate cannot enter the active site, is called a(n)

Question

Quizplus · Accepted Answer

A compound that changes the shape of an enzyme's active site is called an allosteric inhibitor. Noncompetitive inhibitors are a type of allosteric inhibitor that binds to a site other than the active site and causes a conformational change that interferes with substrate binding. Options A, B, and E all refer to different types of inhibitors, but they do not fit the description given in the question stem. Option C refers to a molecule that is required by an enzyme to carry out its catalytic function, and does not fit the description of an inhibitor.
