The addition of an effector to an enzyme that acts as a K system of the MWC model causes the half-maximum velocity (K_0.5) to ____ and V_max to ____. A) remain constant; remain constant B) remain constant; change C) change; remain constant D) change; change E) none of the above

Question

Quizplus · Accepted Answer

The addition of an effector to an enzyme that acts as a K system of the MWC model can change the affinity of the enzyme for the substrate (K_0.5), but it does not affect the maximum velocity (V_max). Therefore, the correct answer is C - change; remain constant.
