Answer #1

Antigen-presenting cells (APCs) are specialised cells (dendritic cells, macrophages and B cells) that can capture, process and present antigen to activate T cells.

Antigen processing:

Antigen processing is the generation of peptide (from antigen) which can bind MHC molecules for presentation to T cells.

Intracellular enzymes degrade antigenic macromolecules into short fragments, which then bind major histocompatibility complex class I and class II molecules.

Antigen presentation:

Antigen presentation is the presentation of antigen as peptide by cell-surface MHC molecules of APCs.

The clonal selection theory states that Multiple Choice B cells can become T cells by appropriate selection. some T cells can produce antibodies by selection. B cells that recognize a given epitope multiply to form a family of identical cells. macrophages multiply to form a clone. cell-mediated immunity depends on processing and presentation of antigen.
