Question

Quizplus · Accepted Answer

All the options listed (allosteric control, feedback inhibition, and covalent modification) are mechanisms by which enzyme catalytic activity can be controlled. Allosteric control involves the binding of a molecule at a site other than the enzyme's active site, which alters the enzyme's activity. Feedback inhibition is a specific form of allosteric control where the end product of a metabolic pathway inhibits an enzyme involved earlier in the pathway. Covalent modification includes the addition or removal of chemical groups (e.g., phosphate, methyl) to regulate enzyme activity.
