So essentially the active Thrombon goes on and cleaves at these four locations. And what that does is it completely removes these two B chains and these two A chains and these four individual chains once they are removed we call them fibrinopeptides. And so we remove these four fibrino peptides and what we form is, is a single active fibrom monomer. So this is basically what it looks like. So we remove these four chains and we form the following active fibrin monomer. So monomer simply means we have a single fibrin molecule in its active form.
