A)play the same role in each type of cell.
B)bind to free antigen.

D)have variable and constant regions.
E)play the same role in each type of cell AND have two binding sites for antigen.

Question

Quizplus · Accepted Answer

Both B and T cell receptors have variable and constant regions, which allow them to bind to specific antigens presented by antigen-presenting cells. However, the specific roles and functions of the receptors differ between B and T cells. B cell receptors are membrane-bound antibodies that recognize and bind to free antigens, while T cell receptors recognize and bind to antigen fragments presented on the surface of other cells.
