All of the following are differences between a B- cell receptor and an antibody produced by a B- cell EXCEPT that
A) B- cell receptors belong to the immunoglobulin protein family while antibodies produced by B- cells do not.
B) B- cells receptors have transmembrane domains while antibodies produced by B- cells do not.
C) B- cell receptors are inserted into the plasma membrane while antibodies produced by B- cells are secreted.

Question

Quizplus · Accepted Answer

Both B-cell receptors and antibodies produced by B-cells belong to the immunoglobulin protein family. The transmembrane domain is a characteristic shared by B-cell receptors, and is how they are anchored into the plasma membrane. B-cell receptors and antibodies differ in their secretion, with B-cell receptors remaining anchored in the membrane while antibodies are secreted into circulation.
