The surface receptors on B and T cells both
A) play the same role in each type of cell.
B) bind to free antigen.
C) have two binding sites for antigen.
D) have variable and constant regions.
E) play the same role in each type of cell AND bind to free antigen.

Question

Quizplus · Accepted Answer

The surface receptors on both B and T cells have variable and constant regions. These regions allow for recognition and binding of specific antigens. However, the roles of these receptors differ between B and T cells. B cells use these receptors, also known as antibodies, to bind and neutralize antigens in extracellular fluids. T cells use their receptors to recognize antigens that have been presented to them by antigen-presenting cells. So, option E is incorrect as the roles played by surface receptors on B and T cells are different. Option A, B and C are also incorrect as they don't include the correct statement about the receptors on B and T cells.
