Which of the following statements about how B and T cells recognize antigen are true? Correct any false statements.
a. B cells only recognize antigen presented by class I or class II MHC molecules.
b. Both cell types can recognize extra-cellular antigen free-floating in solution.
c. Both cell types recognize extracellular matrix-bound antigens.
d. T cells only recognize antigen presented by class I or class II MHC molecules.
Homework Answers
Answer: d. T cells only recognize antigen presented by class I or class II MHC molecules.
B cells have immunoglobins that can help them identify antigens in extracellular spaces. They can also be activated by T cells. T cells, however, can only be activated by a combination of antigens and an accompanying MHC molecules on the surface of another cell.

Adaptive Immunity: Second Line of Defense—Cellular Defenses The T-cell receptors and CD4 and CD8 molecules interact with major histocompatibility complex (MHC) proteins. MHC proteins are found on most cells of the body. There are two variations, or classes, of MHC proteins. MHC class I is expressed on the surface of most cells of the body such as skin cells, liver cells, and others. Should a cell become infected with a virus, viral antigens are processed in the cells and expressed...
