Question

Allosteric modification is termed as regulation of enzyme activity by binding any effector molecule to enzyme at other than its active site. It does not change the concentration of enzyme, rather changes its activity

Answer 1

Allosteric enzymes are enzymes that change their conformational ensemble upon binding of an effector, which results in an apparent change in binding affinity at a different ligand binding site. ... The site to which the effector binds is termed the allostericsite.
