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-cell receptors are inserted into the plasma membrane while antibodies produced by B-cells are secreted.
C)B-cells receptors have transmembrane domains while antibodies produced by B-cells do not.

Question

Quizplus · Accepted Answer

B-cell receptors and antibodies are structurally similar and belong to the immunoglobulin protein family. The main difference between them is that B-cell receptors are anchored to the plasma membrane, while antibodies are secreted. Additionally, B-cell receptors have a transmembrane domain that anchors them to the plasma membrane, while antibodies lack this domain. However, both B-cell receptors and antibodies can bind to antigens and initiate an immune response.
