The ________ theory explains cooperative binding by suggesting all subunits of a given protein have the same conformation,either all R or all T.
A)concerted
B)entropy-driven
C)sequential
D)simultaneous

Question

Quizplus · Accepted Answer

The concerted theory, also known as the symmetry theory or MWC model, proposes that all subunits of a protein with multiple subunits exist in either a relaxed (R) or tense (T) conformation, and cooperativity arises from the transition of all subunits between these two distinct states. Therefore, the correct answer is A, the concerted theory. The other choices (entropy-driven, sequential, simultaneous) do not accurately describe this model of cooperative binding.
