Which is not correct concerning the models that are accepted to describe cooperative binding?
A)   In the sequential model, the binding of a ligand changes the conformation of the subunit to which it binds, which in turn induces a change in neighboring subunits.
B)   All known allosteric proteins exhibit either the concerted or sequential model exclusive of the other.
C)   Both models incorporate a low affinity T-state and a higher affinity R-state.
D)   Both models explain the sigmoid-shaped binding curve.
E)   In the concerted model, all molecules exist either in the T-state or the R-state.
