The substrate is transformed into one or more … WebWhen a substrate binds to one enzymatic subunit, the rest of the subunits are stimulated and become active. Ligands can either have non-cooperativity, positive cooperativity or negative cooperativity. A significant portion of enzymes function such that their properties can be studied using the Michaelis-Menten equation.
