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 usually associated with an enzyme with more than one subunit. Allosteric enzymes have a regulatory site that is separate from the active site and can bind allosteric modulators, causing conformational changes that affect enzyme activity. This type of regulation is often observed in enzymes with multiple subunits, where the allosteric site is located on a different subunit than the active site.
