How is a T-cell receptor different from a B-cell receptor?
A)T-cell receptors must have antigen broken down inside a cell and presented to them by a Major Histocompatibility Complex (MHC)molecule.
B)B-cell receptors must have antigen broken down inside a cell and presented to them by a Major Histocompatibility Complex (MHC)molecule.
C)T-cell receptors are composed of 4 protein chains (pieces),while B-cell receptors are composed of only 2 pieces.
D)T-cell receptors are eventually secreted into the bloodstream by activated T-cells,whereas B-cell receptors are not; they always stay with the B-cell.
