Quizplus · Accepted Answer

The arrow in the diagram indicates the antigen binding site of an antibody, which recognizes and binds specifically to an antigen. The complement binding site of an antibody is located on the Fc region, while the binding sites of MHC and T cell receptors are typically located on different regions of antigen presenting cells and T cells, respectively.
