Question

an antigen presenting cell presents antigen to a t helper cell __________. multiple choice inside a vesicle on its surface on a class - i mhc on its surface on a class - ii mhc on its surface attached to an antibody on its cd8 receptor

Explanation:

Antigen - presenting cells (APCs) such as dendritic cells, macrophages, and B - cells present antigens to T - helper cells. Class - II major histocompatibility complex (MHC) molecules are specifically involved in presenting antigens to T - helper cells. Class - I MHC is mainly for presenting antigens to cytotoxic T - cells. Antigens are not presented inside a vesicle to T - helper cells. Antibodies are not directly involved in presenting antigens to T - helper cells in this context. CD8 receptors are on cytotoxic T - cells, not relevant for T - helper cell antigen - presentation by APCs.

Answer:

on its surface on a class - II MHC
