Verified step by step guidance

Begin by understanding the concept of enzyme regulation. Enzymes can be regulated by molecules that bind to sites other than the active site, affecting their activity.

Identify the term 'allosteric activation'. Allosteric regulation involves the binding of a molecule at a site other than the active site, which can either inhibit or activate the enzyme's function.

Differentiate between types of enzyme inhibition: feedback inhibition, competitive inhibition, and noncompetitive inhibition. Feedback inhibition involves the end product of a pathway inhibiting an enzyme involved earlier in the pathway. Competitive inhibition occurs when a molecule competes with the substrate for binding at the active site. Noncompetitive inhibition involves a molecule binding to a site other than the active site, reducing enzyme activity.

Understand cooperativity, which is a form of enzyme regulation where the binding of a substrate to one active site affects the activity at other active sites within the same enzyme molecule.

Recognize that allosteric activation is distinct from inhibition. It involves the binding of a molecule at an allosteric site, enhancing the enzyme's activity, stabilizing its active form, and increasing its efficiency.
