Question

Quizplus · Accepted Answer

Allosteric proteins often display cooperativity, which is a characteristic feature where the binding of a substrate to one active site affects the binding of substrate to other active sites within the same molecule. This is different from the hyperbolic kinetics described by the Michaelis-Menten model, which is typically observed in non-allosteric enzymes. Allosteric proteins do not always consist of identical subunits; they can be made up of different subunits that work together.
