Question

an allosteric interaction between a ligand, e.g. O2 and a protein is one in which: 24. An allosteric interaction between a ligand, e.g. O2 and a protein is one in which: A. binding of a molecule to a binding site affects binding of additional molecules to the same site B. binding of a molecule to a binding site affects binding properties of another site on the protein C. binding of the ligand to the protein is covalent D. multiple molecules of the same ligand can bind to the same binding site. E. two different ligands can bind to the same binding site.

Explanation / Answer

Ans B . binding of a molecule to a binding site effects binding proerties of another site on the protein .

The effector molecule binds to the allosteric site , which results in conformational change in the protein dynamics , such that the binding of other molecules on the active sites on the protein are affected .

Allosteric regulations are usually a part of the feedback mechanisms .
