Allosteric effectors activate or inactivate enzymes by changing the shape of the enzyme's active site.

Question

Quizplus · Accepted Answer

Allosteric effectors are molecules that bind to a specific site on the enzyme, known as the allosteric site, which is different from the active site. This binding causes a conformational change in the enzyme, altering the shape of the active site and either increasing or decreasing its affinity for the substrate. This change in shape can activate or inhibit the enzyme, depending on the specific allosteric effector involved.
