Allosteric enzymes are which _______(a) Have single subunit(b) Have multiple subunits(c) Follows Michaelis-Menten kinetics(d) Do not affect the binding affinityI have been asked this question in an interview for job.I want to ask this question from Enzymes as Biological Catalysts in portion Bioenergetics, Enzymes, Metabolism, Genes, Chromosomes and Genomes of Cell Biology

Answer»

Right CHOICE is (b) Have multiple subunits

For explanation: ALLOSTERIC enzymes are enzymes that change conformation upon binding of an effector and AFFECTS the binding affinity at a different binding site. Allosteric enzymes are the exception to Michaelis-Menten KINETICS and usually has multiple coupled subunits or DOMAINS.
