Allosteric Enzyme Regulation is Usually Associated With

Question

Allosteric enzyme regulation is usually associated with
A) lack of cooperativity.
B) feedback inhibition.
C) activating activity.
D) an enzyme with more than one subunit.
E) the need for cofactors.

Accepted Answer

Allosteric enzyme regulation is commonly associated with enzymes that have more than one subunit. This allows for regulation of enzyme activity through the interaction between subunits and regulatory molecules.

Answer: B
 Feedback inhibition is a type of allosteric regulation where the end product of a metabolic pathway inhibits the activity of an upstream enzyme in the pathway. This helps to maintain homeostasis by preventing excess accumulation of the end product.
