a. they have a y-shape structure with light chains and heavy chains
b. they have constant (conserved) and variable ends in their protein structure
c. they occur in a large variety in order to recognize and neutralize diverse infectious agents
d. all immunoglobulin proteins produced by b cells are secreted

Answer 1

The correct statement concerning immunoglobulin proteins produced by B cells that is not correct is d. all immunoglobulin proteins produced by B cells are secreted.

Step-by-step explanation:

The correct statement concerning immunoglobulin proteins produced by B cells that is not correct is d. all immunoglobulin proteins produced by B cells are secreted.

B cells produce two types of immunoglobulin proteins: membrane-bound immunoglobulins, which are part of B cell receptors, and soluble immunoglobulins, which are secreted into the blood and other bodily fluids.

Only some of the immunoglobulin proteins produced by B cells are secreted, while others remain as membrane-bound receptors on the surface of B cells.
