In allosteric enzymes, the location of catalytic and regulatory sites are
EXPLANATION
Allosteric Regulation, Covalent Modification,
- Anatomy of Allosteric Enzyme Subunits:
- Unlike classical Michaelis-Menten enzymes where effectors bind the active site, allosteric enzymes possess distinct, spatially separated domains or subunits:
- Catalytic (Active) Site: Binds the specific substrate molecule and executes catalysis.
- Allosteric (Regulatory) Site: Distinct physical pocket that reversibly binds positive or negative allosteric effectors (modulators).
- Effector binding induces a conformational change (quaternary transition between $T$ and $R$ states) that alters substrate binding affinity at the catalytic site.
- nalysis:
- (Different): Correct location of catalytic and regulatory sites.
