How is the central portion of a T cell receptor complex functionally analogous to the center of the B cell receptor complex?
A)It has two pieces (chains),just like a B-cell receptor.
B)Both receptors bind epitopes (small amino acid sections of antigen molecules).
C)Both bind structures directly on the surface of microbes.
D)Both can be secreted from lymphocytes to bind to pathogens under certain situations.

Question

Quizplus · Accepted Answer

The central portion of both T cell and B cell receptor complexes contain variable regions that bind to specific epitopes on antigen molecules. Therefore, both receptors are functionally analogous in their ability to recognize and bind to specific antigens.
