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
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.
calcium ions bind to troponin, causing conformational changes in troponin that allow tropomyosin to move away from the myosin binding sites on actin. Once the tropomyosin is removed, a cross-bridge can form between actin and myosin, triggering contraction
