Question

Allosteric enzymes are which _______

(a) Have single subunit

(b) Have multiple subunits

(c) Follows Michaelis-Menten kinetics

(d) Do not affect the binding affinity

I 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 1

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.
