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. (If you are not sure what some of the items are, see Hint 2.)

Answer 1

Answer:

Hi! Your question is incomplete but I guess the exercise you are refering to is the one I attached to this answer. I hope this answer helps you:

B cells - Humoral response

Plasma cells - Humoral response

antibodies - Humoral response

Cytotoxic T cells - cell-mediated response

Helper T cells and cytokines - both

memmory cells - Both

antigen-presenting cells - Both

Explanation:

Acquired immunity involves humoral immune response and a cell-mediated immune response. The two responses act together, they are interconnected.

- B cells and T cells recognize and bind to an antigen because of the antigen receptors in plasma that allow this response. So, extracellular macromolecules are involved in this activation. This is a Humoral response.

- Plasma cells are the effector cells of the humoral response.

- Antibodies are secreted by plasma cells and tagg the foreign pathogen, so, they belong to humoral response.

- Cytotoxic T cells are the effector cells of the cell-mediated response

- Helper T cells are active in both responses, they stimulate humoral and cell-mediated responses with cytokines.

- The memory cells are produced by clonal selection, they contribute to immunological memory and they belong to both responses. They help increasing the speed of an inmmune response and also increasing the effectiveness of it.

- Antigen-presenting cells could be in humoral or cell-mediated responses.
