Enzymes and kinetics
Enzymes accelerate reactions by stabilizing lower-energy reaction pathways without shifting the overall equilibrium of a reversible reaction.

Catalysis
An enzyme active site binds substrates and stabilizes transition states, increasing reaction rate while remaining regenerated at the end.
Michaelis–Menten behavior
For applicable single-substrate systems, velocity approaches Vmax as substrate concentration rises; Km is the substrate concentration at half Vmax under model assumptions.
Competitive inhibition
A classic competitive inhibitor raises apparent Km without changing Vmax when sufficient substrate can overcome inhibitor binding.
Allosteric regulation
Multisubunit enzymes may show cooperative or complex kinetics, so a simple hyperbola does not capture all biological regulation.
