A substrate finds a selective site. Shape, charge, hydrogen bonds, and hydrophobic interactions make some encounters productive.

More substrate raises encounter frequency until active sites approach saturation. An inhibitor lowers the available catalytic capacity in this teaching model.
The Michaelis–Menten curve is a simplified steady-state model. Real enzymes can have multiple substrates, cooperativity, allostery, crowding, and regulation.
