The process of stabilizing the structure of an enzyme in its active form by the binding of a molecule outside the active site is an example of __________.

• A. feedback inhibition
• B. competitive inhibition
• C. noncompetitive inhibition
• D. cooperativity
• E. allosteric activation

Answer: (E)

Verified step by step guidance

1. Understand the concept of enzyme regulation: Enzymes can be regulated by molecules that bind to sites other than the active site, affecting their activity.
2. Identify the type of regulation: The process described involves stabilizing the enzyme's active form by binding a molecule outside the active site.
3. Differentiate between inhibition types: Feedback inhibition and competitive inhibition involve reducing enzyme activity, while noncompetitive inhibition involves binding at a site other than the active site to reduce activity.
4. Explore cooperativity: Cooperativity involves the binding of a substrate to one active site affecting the activity at other sites, often seen in multi-subunit enzymes.
5. Recognize allosteric activation: Allosteric activation occurs when a molecule binds to an enzyme at a site other than the active site, enhancing its activity or stabilizing its active form.
