Complex II contains five prosthetic groups and four different protein subunits;
a. Subunits A and B extend into the matrix; they contain three 2Fe-2S centers, bound FAD, and a
binding site for the substrate, succinate
b. Subunits C and D are integral membrane proteins, contain a heme group, heme b, and a binding
site for ubiquinone,
