Question

Which of the following statements about T lymphocytes is FALSE? Which of the following statements about T lymphocytes is FALSE? T lymphocytes are called such because they mature in the thymus. There are three types of T lymphocytes. T lymphocytes produce antibody molecules. T lymphocytes have TCRs that recognize antigen only if it is bound to MHC. T lymphocytes directly attack cells and produce the cell-mediated immune response. Request Answer

Answer 1

The false statement about T lymphocytes is that 'T lymphocytes produce antibody molecules.' This function is actually performed by B lymphocytes, while T lymphocytes are involved in cell-mediated immunity.

Step-by-step explanation:

The false statement about T lymphocytes is that 'T lymphocytes produce antibody molecules.' This is incorrect because it is actually B lymphocytes, not T lymphocytes, that are responsible for the production of antibody molecules involved in the body's defense against pathogens (humoral immunity). T lymphocytes, on the other hand, are primarily involved in cell-mediated immunity. They have T-cell receptors (TCRs) that recognize antigens presented by Major Histocompatibility Complex (MHC) molecules on the surface of other cells, which is essential for their role in the immune response. T lymphocytes include helper T cells, regulatory T cells, and cytotoxic T cells, each performing different functions in the immune system.

While both B cells and T cells are crucial components of the adaptive immune system, their functions and processes of maturation differ. T lymphocytes do not produce antibodies, but rather perform functions such as assisting other immune cells, regulating immune responses, and destroying infected or cancerous cells.

Answer 2

The false statement is: T lymphocytes produce antibody molecules

B lymphocytes produce antibody molecules.

B cells and T cells or lymphocytes are both cells of the adaptive immune system. Progenitor T cells mature (start to express T cell receptors TCRs, CD4 /CD8 receptors) into T cells in lymphoid organ-thymus. T cell can recognize only those antigens that are presented on antigen-presenting cells, on their surface MHC molecules.

There are three types of T cells: Helper T cells,Cytotoxic T cellsand T regulatory cells.
