Question

In the concerted model for allosteric enzymes, if the taut form of the enzyme cannot bind substrate then A) K_T < K_R B) L = R/T C) c = 0 D) an inhibitor must be present E) none of these

Quizplus · Accepted Answer

In the concerted model, the enzyme can exist in a relaxed (R) state or taut (T) state, with all subunits undergoing a conformational change simultaneously. According to the model, there is no binding of substrate to the T state, meaning that the concentration of the T state will be zero in the presence of substrate. Therefore, the concentration of the T state (c) would be equal to zero, making choice C the correct answer. Choices A, B, D, and E are not relevant to the given information.
