Figure 2.

Plots of the Michaelis‐Menten model, illustrating equation 1. A) Velocity vs. substrate concentration under constant enzyme concentration. The substrate affinity K_m corresponds to the substrate concentration at which the reaction reaches half of v_max, which is the velocity at infinite substrate concentration. B) v_max vs. enzyme concentration. The reaction is first‐order with respect to enzyme concentration, with the rate constant k_cat.
