Option (B), (D) and (E).

Explanation:

Allosteric enzymes may be defined as the enzymes that an change their conformation ensemble after binding to an effector molecule. They play important role in cell signalling and metabolic pathways.

Allosteric enzymes do not obey Michaelis - Menten kinetics. They have two binding sites regulatory site and active site. They contain multiple subunit and exist in more active and less active form depending on the type of substrate and regulatory molecule.

Thus, the correct answer is option (B), (D) and (E).
