Effect of cooperative substrate binding on enzyme kinetics

Description
(a) Comparison of v vs. curves for a noncooperative enzyme and an allosteric enzyme with cooperative binding. The two enzymes are assumed to have the same Vmax.

(b) Lineweaver-Burk Plot. The T state has a high KM (Vmax is achieved at higher ). As more S is bound, the equilibrium shifts toward the R state, which has a lower KM.
