Final answer:
The antigen receptor on a B cell is an immunoglobulin, which is Y-shaped and basically a membranebound antibody. B-cell receptors (BCRs) are membrane-bound monomeric forms of IgD and IgM that bind specific antigen epitopes with their Fab antigen-binding regions. Each B cell has only one kind of antigen receptor, which makes every B cell different.
Step-by-step explanation:
The antigen receptor on a B cell is an immunoglobulin, which is Y-shaped and basically a membranebound antibody. B-cell receptors (BCRs) are membrane-bound monomeric forms of IgD and IgM that bind specific antigen epitopes with their Fab antigen-binding regions. The B cell receptor has two heavy chains and two light chains connected by disulfide bonds into a basic “Y” shape. Each B cell has only one kind of antigen receptor, which makes every B cell different.
