WebApr 28, 2024 · Substrate (s) bind to the active site at the heme group, which induces a conformational change of the enzyme's active site. Reductases are then responsible for electron transfer from NAD (P)H. Oxygen binds to the ferrous-heme group following the reduction of iron. WebMar 5, 2024 · Enzymes bind both reactant molecules (called the substrate), tightly and specifically, at a site on the enzyme molecule called the active site (Figurebelow). By binding reactants at the active site, enzymes also position reactants correctly, so they do not have to overcome intermolecular forces that would otherwise push them apart.
