A protein displays allosteric regulation.Which of the following is true?
A) Each subunit is either in the T state or the R state, but does not switch from one state to the other.
B) Each subunit can exist in more than one conformation.
C) When the protein binds to a positive allosteric effector, the subunits are more likely to be in the T state.
D) A subunit must be in the R state in order to bind ligand.

Allosteric regulation involves a change in the conformation of a protein as a result of ligand binding. This change in conformation can be transmitted to other parts of the protein, affecting its activity. In the case of allosteric proteins, each subunit can exist in more than one conformation, allowing for the protein to transition between active and inactive states. This allows for greater flexibility and responsiveness to changes in the environment.
