In reference to enzyme activities,repressors _____ the active site,while activators ________ it.

Question

Quizplus · Accepted Answer

Repressors bind to the active site of enzymes, blocking substrate binding and thus disrupting enzyme activity. On the other hand, activators bind to allosteric sites on enzymes, inducing conformational changes that increase the affinity of the active site for substrate, resulting in restored or increased enzyme activity. Therefore, option C is correct as it represents the correct relationship of repressors disrupting enzyme activity by blocking the active site and activators stimulating enzyme activity by inducing a conformational change in the enzyme.

In Reference to Enzyme Activities,repressors _____ the Active Site,while Activators
