WebWhen enzymes contain more than one active site, the binding of a substrate molecule to the first site may influence substrate binding to a second site. Binding of the second substrate may influence binding of a third, and so on. … Cooperative binding occurs in molecular binding systems containing more than one type, or species, of molecule and in which one of the partners is not mono-valent and can bind more than one molecule of the other species. In general, molecular binding is an interaction between molecules that results in a stable physical association between those molecules. Cooperative binding occurs in a molecular binding system where two or more ligand molecules … WebSep 7, 2024 · Cooperativity describes the changes that occur when a binding site of one of these structures is activated or deactivated affecting the other binding sites in the same molecule.
