Question

Quizplus · Accepted Answer

Allosteric proteins have distinct regulatory sites that can bind effectors, which can cause conformational changes that affect the activity of the protein's multiple functional sites. This results in cooperativity, where the binding of a ligand at one site affects the binding or activity of the protein at another site. Allosteric proteins may consist of multiple subunits, but they do not necessarily have to be identical.
