Question

Which of these molecules is incorrectly paired with a source? A.)interferons - virus-infected cells B.)chemokines - cytotoxic T cells C.)antibodies - B cells D.)lysozyme - tears E.)cytokines - helper T cells

Answer 1

The incorrect pairing is chemokines - cytotoxic T cells, as chemokines can be produced by various cell types, not exclusively by cytotoxic T cells.

Step-by-step explanation:

The question concerns the sources of various molecules involved in the immune system. The pairing you provided that is incorrect is B.) chemokines - cytotoxic T cells. Chemokines are signaling proteins secreted by cells, but they are not specifically produced only by cytotoxic T cells; instead, they can be produced by a variety of cell types. Cytotoxic T cells are primarily involved in killing virus-infected cells directly rather than producing chemokines.

For reference, let's clarify the correct pairings:

Interferons are indeed produced by virus-infected cells and help to protect neighboring cells from viral infection.

Antibodies are produced by B cells and are important in recognizing and neutralizing pathogens.

Lysozyme is an enzyme found in various secretions such as tears and saliva that destroys the cell walls of certain bacteria.

Cytokines, which include interferons, can be produced by helper T cells as well as other cell types, aiding in the regulation of the immune response.
