Quizplus · Accepted Answer

Inhibitors or activators of enzyme-catalyzed reactions can bind reversibly to an enzyme's allosteric site, causing a conformational change that affects the enzyme's activity. This can either decrease (inhibition) or increase (activation) the enzyme's catalytic activity. This is a common mechanism for regulating enzyme activity and is often used in metabolic pathways.
