K_M A)is the concentration of substrate where the enzyme achieves ½ V_max. B)is equal to Ks. C)measures the stability of the product D)is high if the enzyme has high affinity for the substrate. E)All of the above are correct.

Question

The Michaelis constant (Km) is defined as the substrate concentration at which the reaction rate is half of its maximum value (Vmax). This is a fundamental concept in enzyme kinetics, reflecting the enzyme's affinity for its substrate indirectly; a lower Km indicates higher affinity.
