water interactions with ions and polar molecules

The Michaelis constant, denoted as $K_m$, is a measure of the substrate concentration at which an enzyme operates at half its maximum velocity. It is used to describe the affinity of the enzyme for its substrate.

Vmax

The maximum rate of an enzyme-catalyzed reaction when the enzyme is saturated with substrate.

enzymes

The maximum rate of reaction that an enzyme can achieve at saturating substrate concentration. Vmax reflects the catalytic capacity of the enzyme.

kcat

The turnover number of an enzyme, representing the maximum number of substrate molecules converted to product per enzyme active site per unit time at saturation.
