Multiple Choice

Which of the following statements is FALSE?

Each B cell has BCRs that bind to a single antigen.

The cell type that secretes antibodies is called a plasma cell.

A BCR allows naive B cells to detect an antigen.

All naive B cells that are close in proximity to an antigen begin to differentiate.

Verified step by step guidance

Understand the role of B cells in the immune system. B cells are a type of white blood cell that play a crucial role in the adaptive immune response by producing antibodies.

Learn about B cell receptors (BCRs). Each B cell has unique BCRs that are specific to a particular antigen, allowing the B cell to recognize and bind to that antigen.

Recognize the function of plasma cells. When B cells are activated by an antigen, they can differentiate into plasma cells, which are responsible for secreting antibodies specific to the antigen.

Understand the process of B cell activation. Naive B cells, which have not yet encountered their specific antigen, use BCRs to detect antigens. Upon detection, they can become activated and differentiate into plasma cells.

Evaluate the false statement: 'All naive B cells that are close in proximity to an antigen begin to differentiate.' This statement is false because only those B cells whose BCRs specifically bind to the antigen will become activated and differentiate, not all B cells in proximity.
