Question

Acquired immunity involves both a humoral immune response and a cell-mediated immune response. To review the definitions of these immune responses, see Hint 1.Sort the items into the appropriate bins depending on whether they are involved in the humoral response, the cell-mediated response, or both the humoral and the cell-mediated responses.a. antigen presenting cellsb. plasma cellsc. memory cellsd. antibodiese. b cellsf. helper T cells and cytokinesisg. cytotoxic T cellsThe categories are humoral response, cell mediated response, and both

Answer 1

Answer:

The correct answers are:

A) Antigen-presenting Cell - both responses.

B) Plasma Cell - humoral immune response.

C) Memory Cells - both responses.

D) Antibodies - humoral response.

E) B Cells - humoral immune response.

F) Helper T Cells - both responses.

G) Cytotoxic T Cells - cell-mediated immune response.

Explanation:

Acquired immunity involves both a humoral immune response and cell-mediated immune response, since these two responses are not independent of each other, but instead "work together" in order to perform a better response.

Humoral immunity is mediated by macromolecules (like antibodies) found in extracellular fluids, and is activated much more quickly than the cell-mediated one, but it doesn't last as long. The Cellular immunity, on the other hands, needs the prior activation of cells such as macrophages and lymphocytes.
